A Review on Depth Wise Nutrients Status in Punjab’s Soils

Punjab, which is well-known for its agricultural output, has significant difficulties in preserving soil fertility in the face of intensive farming methods. The depth-wise distribution of nutrients in Punjab's soils is examined in this review, which is important to comprehend agricultural sustainability. Several agricultural zones provided soil samples, which were then examined for important macronutrients (N, P, and K) and micronutrients (Zn, Fe, Mn, and Cu). Recent article contains status of soil nutrients of Punjab emphasizing mostly deficits elements that may hinder crop growth. It was also reflected by the researchers that because of intensive farming methods and insufficient replenishing, nitrogen levels become low with time. Analyzing the d ata published by the research papers it was observed that potassium and phosphorus levels were moderate, although significant deficits were found in several locations. Micronutrient investigation revealed that iron and manganese levels were comparatively adequate, but there was a general shortage in zinc in this region. The review emphasizes that in order to maximize soil fertility and increase crop yields, region-specific nutrient management practices are necessary. The application of organic amendments, balanced fertilization techniques, and routine soil testing to identify and correct nutrient imbalances are among the recommendations. In order to maximize fertilizer applications, improve nutrient use efficiency, and guarantee Punjab's long-term agricultural productivity and environmental sustainability, these variations must be taken into consideration. This review emphasizes how crucial it is to implement customized soil management plans in order to prevent nutrient depletion and maintain the area's agricultural future.
