HORTICULTURE

Detailed explanation-1: -Soil testing is important for determining the portion of the crop nutrient requirement that can be supplied from the soil. Soil testing is most effective in regard to nutrients that are not highly mobile in the soil.

Detailed explanation-2: -Leaf analysis is the chemical testing of leaves to provide nutrient composition of the sample. It provides a general indication of the nutrient levels in the plant, reflecting what the plant was able to extract and store during the current season.

Detailed explanation-3: -Plant tissue analysis is determining, in a laboratory, the total elemental content of the whole plant or parts of plants, typically leaves or petioles (leaf stem). In field crops, plant tissue analysis, in conjunction with a soil test program, can serve as a check on a fertilizer program.
