Question

How will you manage the crop if the soil is deficient in P?

Answer 1

Phosphorus plays a vital role in plant reproduction as a result gives grain production.The concentration of soluble phosphate in the soil solution is very low, and phosphorus is relatively immobile in the soil.This plays a major role because plants take up phosphorus only from soil.

Correction and prevention of phosphorus deficiency involves increasing phosphorus content in soil .planters introduce bone meal, rock phosphate,manure, and phosphate-fertilizers. Plant species and different plants within in the same species react differently to low levels of phosphorus in soil. Greater expansion of root systems generally correlate to greater nutrient uptake. Plants within a species that have larger roots are genetically advantaged and less prone to phosphorus deficiency. These plants can be cultivated and bred as a long term phosphorus deficiency prevention method. In conjunction to root size, other genetic root adaptations to low phosphorus conditions such as mycorrhizal symbioses have been found to increase nutrient intake. These biological adaptations to roots work to maintain the levels of vital nutrients. In larger commercial agriculture settings, variation of plants to adopt these desirable phosphorus intake adaptations may be a long-term phosphorus deficiency correction method. Regular ph check can help us know the amount of phosphorus present.
