What's new
Liming economic calculator
A liming economic calculator is now available to help farmers:
- Determine application rates for different liming products to raise soil pH to the target level for crop production
- Compare costs for different liming products, factoring in products, hauling, and application expenses
- Identify the most economical liming product option by ranking products based on cost, net return, benefit-cost ratio, and payback period
Fertilizer cost calculator
A fertilizer cost calculator is now available to help farmers:
- Compare the cost of different fertilizers on a $/lb of nutrient basis
- Develop the most cost-effective fertilizer blends to meet crop demands
- Determine your fertilizer rate and cost/acre
- Calculate how much fertilizer you need for a specified area and the total cost
What is nutrient management?
Nutrient management is an essential step in maintaining soil health and optimizing crop yield and quality. Nutrient management involves applying the right type of nutrient sources, such as manure, fertilizer or compost in the right amount, in the right place and at the right time.
Soil sampling and testing is often a first step in nutrient management and a proactive approach to monitor and maintain soil health, informing farmers how much manure (or alternative nutrient) to apply, and where. A major reason for soil testing is to evaluate soil fertility, the ability of the soil to supply crops with nutrients.
Understanding soil test results can guide decisions and help to:
- Know what nutrients your crops will require
- Avoid over-application of nutrients and unnecessary costs
- Prevent water contamination and greenhouse gas emissions
- Maintain optimum pH, micronutrients in your soil
