VRT involves the application of fertilizers at variable rates within a field to match soil nutrient status and crop demand. The benefits are reduced fertilizer costs, minimized environmental impact, and maximized crop yields.

Soil pH management ensures the soil's acidity or alkalinity is within the optimal range for crop growth. Benefits include enhanced nutrient availability, improved soil structure, and reduced metal toxicity.

Cover cropping involves growing certain plants to cover the soil rather than for harvest. Benefits include nutrient retention, erosion control, and soil organic matter enhancement.

Integrated Nutrient Management (INM) is a balanced approach combining biological, organic, and inorganic inputs. Benefits include sustainable soil health, reduced reliance on chemical fertilizers, and better crop yields.

The 4R Nutrient Stewardship framework promotes applying the Right source of nutrients at the Right rate, Right time, and Right place. Benefits include environmental stewardship, enhanced nutrient use efficiency, and economic gains.

Biofertilizers are microbial inoculants that enhance nutrient supply to the crops through biological nitrogen fixation or solubilization of soil nutrients. Benefits include reduced chemical dependency, improved soil health, and cost savings.

Yield mapping is a technology that records crop yield data as the harvest occurs. Benefits include identifying variability within fields, informing management practices, and improving yield predictability.

Fertilizers can be organic or inorganic with varying ratios of N-P-K (nitrogen, phosphorus, potassium). Benefits of choosing the correct type include enhanced soil fertility, reduced nutrient leaching, and increased crop yield.

Crop rotation is the practice of growing different types of crops in the same area across a sequence of seasons. Benefits include nutrient cycling, reduced disease pressure, and improved soil structure.

Remote sensing uses satellite or aerial imagery to monitor crop health and soil conditions. Benefits include precise application of inputs, reduced resource waste, and improved crop monitoring.

Plant tissue testing analyzes the concentration of essential nutrients in plant tissues, indicating if a plant is deficient or has an adequate supply of nutrients. Benefits include precise nutrient management and improved plant health.

Precision irrigation is the targeted application of water to match the specific needs of each plant. Benefits include reduced water usage, decreased likelihood of nutrient leaching, and optimized plant growth.

Soil testing is the analysis of a soil sample to determine nutrient content, composition, and other characteristics. Benefits include tailored fertilizer application, cost savings, and environmental protection.

Nutrient budgeting involves calculating the input of nutrients into a cropping system and the removal of nutrients via the harvested crops. Benefits include efficient nutrient usage, reduced costs, and limited environmental impact.
