The main difference between solution (1) and solution (2) is the different use of nitrate-nitrogen and ammonium-nitrogen based stock solutions to prepare the respective Hoagland solution of interest. Accordingly, the original 1933 and the modified concentrations of 1938 and 1950 for each essential element and sodium are shown below, the ...

CULTAN Fertilization, or Controlled Uptake Long Term Ammonium Nutrition, is a type of injection fertilization where the entire amount of nitrogen needed for a plant to grow is injected at one time. During CULTAN fertilization, nitrogen is applied at the first signs of nitrogen deficiency in plants. [ 1 ]
Nitrogen deficiency is a deficiency of nitrogen in plants. This can occur when organic matter with high carbon content, such as sawdust, is added to soil. [1] Soil organisms use any nitrogen available to break down carbon sources, making nitrogen unavailable to plants. [1] This is known as "robbing" the soil of nitrogen. All vegetables apart ...

Anabaena, in association with the water fern Azolla, can contribute nitrogen up to 60 kg/ha/season and can also enrich soils with organic matter. [ 3 ] [ 4 ] Seaweeds are rich in various types of mineral elements (potassium, phosphorus, trace elements, etc.), hence they are extensively used as a form of manure replacement by people of coastal ...
Fertilizer trees are used in agroforestry to improve the condition of soils used for farming. As woody legumes, they capture nitrogen from the air and put it in the soil through their roots and falling leaves. [1] They can also bring nutrients from deep in the soil up to the surface for crops with roots that cannot reach that depth. [2]
