Describe the Soil factors in fertilizer requirements
Physical condition of the soil, soil fertility and soil reaction are three important soil factors. A poor physical condition does not allow efficient use of fertilizer nutrients due to impeded drainage, restricted aeration and unfavourable soil temperature. The coarse textured soils are usually poorer in available nutrients than fine textured soils and therefore it is necessary to apply nitrogenous, phosphatic and potassic fertilizers more frequently in such cases. The higher the fertility of soil, lower is the response of crops to fertilizers. The soil reaction is very important in selection of the right type of phosphatic fertilizers.
