Dry, overheated, and sunburnt plants are most susceptible to fertilizer burns. [6] There are five ways that the use of fertilizer could cause burns. Use of too much fertilizer of the correct salt index. This causes a buildup of salts and nutrients in the soil and thus a fertilizer burn from low osmotic pressure. [1]
Over time, the nutrients fixed by soil microbes and humus are released and available to crops. Nutrients from residue are not fully recovered by crops. Just like fertilizer nutrients, nutrients released from crop residue into the soil are susceptible to losses such as leaching (N and S), denitrification (N), immobilization (N, P, K and S), and ...
Borax, Boric Acid or Solubor can be dissolved in water and sprayed or applied to soil in blended dry fertilizer. Excess boron is toxic to plants so care must be taken to ensure correct application rate and even coverage. [7] While boron may be sprayed on leaves, excess will cause plant damage.

Microbes can make nutrients and minerals in the soil available to plants, produce hormones that spur growth, stimulate the plant immune system and trigger or dampen stress responses. In general a more diverse soil microbiome results in fewer plant diseases and higher yield.
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 from nitrogen fixing legumes are prone to this disorder. Nitrogen deficiency can be prevented by using grass mowings as a mulch or foliar feeding with manure.
In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.
