[Korean Farmers' News Reporter Kim Young-min] It has been confirmed that the yield increased significantly after measuring the plowing depth and analyzing the nutrients in the soil before cultivating greenhouse strawberries and green peppers, and issuing prescriptions based on the results. The National Institute of Agricultural Science announced that it has established an "on-site diagnosis and prescription method" to prevent the decrease in crop weight, quality, and soil health due to nutrient accumulation in the soil of winter greenhouse strawberry and green pepper cultivation areas. The on-site diagnosis and prescription method is a technology that measures the plowing depth before crop cultivation and analyzes the water-soluble components of the soil during the cultivation period to prescribe nutrients. This technology involves measuring the plowing depth with a probe before plowing the soil.
