Fertigation
Fertigation is the wikt:injection, injection of fertilizers, used for soil amendments, water amendments and other water-Solubility, soluble products into an irrigation system. Chemigation, the injection of chemicals into an irrigation system, is related to fertigation. The two terms are sometimes used interchangeably however chemigation is generally a more controlled and regulated process due to the nature of the chemicals used. Chemigation often involves insecticides, herbicides, and fungicides, some of which pose health threat to humans, animals, and the environment. Uses Fertigation is practiced extensively in commercial agriculture and horticulture. Fertigation is also increasingly being used for landscaping as dispenser units become more reliable and easier to use. Fertigation is used to add additional nutrients or to correct nutrient deficiencies detected in plant tissue analysis. It is usually practiced on the high-value crops such as vegetables, turf, fruit trees, and orn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drip Irrigation
Drip irrigation or trickle irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the rhizosphere, root zone and minimize evaporation. Drip irrigation systems distribute water through a network of valves, pipes, tubing, and emitters. Depending on how well designed, installed, maintained, and operated it is, a drip irrigation system can be more efficient than other types of irrigation systems, such as surface irrigation or sprinkler irrigation. As of 2023, 3% of the world's farmers use drip irrigation. History Ancient China Primitive drip irrigation has been used since ancient times. ''Fan Shengzhi shu'', written in China during the first century BCE, describes the use of buried, unglazed clay pots filled with water, sometimes referred to as Olla#Use in irrigation, Ollas, as ...

Fertilizer Injecter
A fertilizer injector is a piece of farming equipment used by farmers to reduce labor when fertilizing a large number of crops. Though this device can be used in a variety of agricultural ways, these injectors are essential in greenhouses and nurseries. This injector is utilized every time the plants are watered, which provides consistency for necessary plant growth. This form of micro-irrigation has become more popular over the past few years, which only further contributes to how unparalleled uniformity this device provides. Farmers accomplish fertilizing large sections of crops by combining water-soluble fertilizer and water in a tank, where it is then expelled by the injectors onto waiting crops. This process is known as fertigation. By injecting a specified amount of concentrated fertilizer into the device, the injector mixes this into what is called a stock solution. To avoid overfertilization of plants that would result in the plant's death, the precise ratio of fertilizer to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fertilizers
A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrition, plant nutrients. Fertilizers may be distinct from Liming (soil), liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and Agrochemical, industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment, or hand-tool methods. Historically, fertilization came from natural or organic sources: compost, Manure, animal manure, Human waste, human manure, harvested minerals, crop rotations, and byproducts of human-nature industries (e.g. Fish meal, fish processing waste, or B ...

Irrigation
Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the olde ...

Water Conservation
Water conservation aims to sustainably manage the natural resource of fresh water, protect the hydrosphere, and meet current and future human demand. Water conservation makes it possible to avoid water scarcity. It covers all the policies, strategies and activities to reach these aims. Population, household size and growth and affluence all affect how much water is used. Although the terms "water efficiency" and "water conservation" are used interchaneably they are not the same. Water efficiency is a term that refers to the improvements such as the new technology that help with the efficiency and reduction of using water. On the other hand, water conservation is the term for the action of conserving water. In short, water efficiency relates to the development and innovations which help use water more efficiently and water conservation is the act of saving or preserving water. Climate change and other factors have increased pressure on natural water resources. This is especially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sustainable Agriculture
Sustainable agriculture is agriculture, farming in sustainability, sustainable ways meeting society's present food and textile needs, without compromising the ability for current or future generations to meet their needs. It can be based on an understanding of ecosystem services. There are many methods to increase the sustainability of agriculture. When developing agriculture within the sustainable food systems, it is important to develop flexible business processes and farming practices. Agriculture has an enormous environmental impact of agriculture, environmental footprint, playing a significant role Greenhouse gas emissions from agriculture, in causing climate change (food systems are responsible for one third of the anthropogenic greenhouse gas emissions), water scarcity, water pollution, land degradation, deforestation and other processes; it is simultaneously causing environmental changes and being impacted by these changes.

Soil Defertilisation
Soil defertilisation refers to the practice of reducing soil fertility in order to reduce the number of plants that can grow on that soil. It is often done on land not intended for agriculture, such as city parks. Benefit On land not intended for agriculture, such as city parks or other communal spaces, undesired plants (weeds) can become a nuisance to the city's communal services, costing effort and money. In some cases, along with soil defertilisation, the soil's pH and water content can be altered. This may create a much different environment, allowing more specialised plants/vegetation to grow and take hold. In practice Soil defertilisation is done by growing specific cover crops (e.g., ''Phacelia'', ''Sinapis alba'', ''Lolium multiflorum ''Lolium multiflorum'' (Italian rye-grass, annual ryegrass) is a ryegrass native to temperate Europe, though its precise native range is unknown. It is a herbaceous annual, biennial, or perennial grass that is grown for silage, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foliar Feeding
Foliar feeding is a technique of feeding plants by applying liquid fertilizer directly to the leaves. Plants are able to absorb essential elements through their leaves. The absorption takes place through their stomata and also through their epidermis. Transport is usually faster through the stomata, but total absorption may be as great through the epidermis. Plants are also able to absorb nutrients through their bark. Foliar feeding was earlier thought to damage tomatoes, but has become standard practice. Effectiveness H. B. Tukey was head of Michigan State University (MSU) Department of Horticulture in the 1950s. Working with S. H. Wittwer, they demonstrated that foliar feeding is effective. Radioactive phosphorus and potassium were applied to foliage. A Geiger counter was used to observe absorption, movement and nutrient utilization. The nutrients were transported at the rate of about one foot per hour to all parts of the plants. A spray enhancer, called a surfactant, can he ...

Bioavailable
In pharmacology, bioavailability is a subcategory of absorption and is the fraction (%) of an administered drug that reaches the systemic circulation. By definition, when a medication is administered intravenously, its bioavailability is 100%. However, when a medication is administered via routes other than intravenous, its bioavailability is lower due to intestinal epithelium absorption and first-pass metabolism. Thereby, mathematically, bioavailability equals the ratio of comparing the area under the plasma drug concentration curve versus time (AUC) for the extravascular formulation to the AUC for the intravascular formulation. AUC is used because AUC is proportional to the dose that has entered the systemic circulation. Bioavailability of a drug is an average value; to take population variability into account, deviation range is shown as ±. To ensure that the drug taker who has poor absorption is dosed appropriately, the bottom value of the deviation range is employed t ...

Cyproconazole
Cyproconazole is an agricultural fungicide of the class of azoles, used on cereal crops, coffee, sugar beet, fruit trees and grapes, and peanuts, on sod farms and golf course turf and on wood as a preservative. It has been used against powdery mildew, rust on cereals and apple scab, and applied by air or on the ground or by chemigation. In the US approval began in 1993, and it was introduced to the market by then Sandoz in 1994, which as of 2000 has been Syngenta. EU approval began in June 2011 and expired after 10 years in May 2021. It is persistent in both soil and water systems. The European Community has classified cyproconazole into carcinogen category 3 as limited evidence, as reproductive toxicant, and as dangerous for the environment, because very toxic to aquatic organisms, causing acute and long-term adverse effects in the aquatic environment. While it is moderately toxic to mammals and most aquatic organisms, earthworms and honeybees, it is highly toxic to bird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium Chloride
Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. KCl is used as a salt substitute for table salt (NaCl), a fertilizer, as a medication, in scientific applications, in domestic water softeners (as a substitute for sodium chloride salt), as a feedstock, and in food processing, where it may be known as E number additive E508. It occurs naturally as the mineral sylvite, which is named after salt's historical designations ''sal degistivum Sylvii'' and ''sal febrifugum Sylvii'', and in combination with sodium chloride as sylvinite. Uses Fertilizer The majority of the potassium chloride produced is used for making fertilizer, called potash, since the growth of many plants is limited by potassium availabil ...
