Soil fertility • harvesting crops removes nutrients from the soil • chemical fertilizer, animal waste, sewage sludge nutrient deficiencies • visual symptoms can give a clue to deficiencies • tissue analysis: identify shortages • at this time it is usually too late to correct.

Soil fertility • harvesting crops removes nutrients from the soil • chemical fertilizer, animal waste, sewage sludge nutrient deficiencies • visual symptoms can give a clue to deficiencies • tissue analysis: identify shortages • at this time it is usually too late to correct. This document discusses methods for evaluating soil fertility, including deficiency symptoms, tissue analysis, and biological tests. tissue analysis involves extracting plant parts with reagents and comparing nutrient concentrations to standards. Fertilizer needs can be determined if know soil test levels and yield potential. increasing fertilizer use efficiency will continue to be a critical goal for small grain farmers. fortunately, there are several strategies to meet this goal, including diversification of cropping system. 31 want more information on soil fertility?. When nitrogen is deficient in the soil, a plant’s older leaves will start to turn yellow (chlorosis) and eventually die. a plant will show purpling in the stem or leaf when phosphorus is deficient in the soil. The document discusses various methods used to evaluate soil fertility, including nutrient deficiency symptoms in plants, plant analysis, biological tests, and soil testing. nutrient deficiency symptoms provide a qualitative measure of availability but can be difficult to diagnose.
