Nutrient Management

A comprehensive guide covering the fundamentals of balanced crop nutrition and the 4R's of nutrient management.
All Things Soil background

All Things Soil

Learn how the world below shapes crop performance through colors, textures and living organisms - and utilize the tools & resources needed to take full advantage.

Soil Defined

Soil occurs naturally and is made up of layers (soil horizons) consisting of minerals and organic matter. Soil feeds the land, allowing plants to grow and thrive.

Soil Sampling

Soil sampling and testing provides an estimate of the capacity of the soil to supply adequate nutrients to meet the needs of growing crops.

Soil Testing

Soil testing is an important tool in high-yield farming. Test results provide the basic facts on which fertilizer to use and determines lime needs.

Soil pH

Soil pH is a measure of the acidity and alkalinity in soils. pH levels range from 0 to 14. The optimal pH range for most plants is between 5.5 and 7.0.

Nutrient Removal Calculator

Each harvest comes with a degree of soil nutrient loss depending on your crop and yield. Discover what deficiencies to be aware of with our Nutrient Removal Calculator.

Nutrient Information background

Nutrient Information

NPK and everything else you need to know from A-Z. Learn about the key nutrients essential for plant health - and how each can be used to optimize yields.


Nitrogen is an essential nutrient for plant growth, development and reproduction. Unfortunately, it’s the most deficient essential plant nutrient worldwide.


Phosphorus is essential for all living organisms. A plant must have phosphorus to complete its normal production cycle.


Potassium is required for plant growth and reproduction. Potash is defined as K₂0 and is used to express the content of various fertilizer materials containing K.

Secondary Nutrients

The need of calcium, magnesium and sulfur has increased due to the demands of today’s high-yield crop systems and are essential to plant productivity.


Micronutrients are essential for plant growth and play an important role in balanced crop nutrition. As important to plant nutrition as primary and secondary nutrients.

Fluid and Dry Fertilizers

When comparing fluid fertilizers vs. dry fertilizers, benefits should be based solely on crop yield obtained when all environmental factors are equal.

Plant Analysis background

Plant Analysis

From monitoring nutrient status to diagnosing likely nutrient problems, plant analysis is a powerful tool for maintaining the health and productivity of your crops.

Plant Analysis

Plant analysis refers to the measurement of essential nutrient content of plant tissue by laboratory analysis. There have been many advances in plant analysis.

4R Stewardship background

4R Stewardship

The right fertilizer source, at the right rate, at the right time, and in the right place. Following the 4Rs can help increase yields and profitability while protecting the environment and improving sustainability.

4R Nutrient Stewardship

4R Nutrient Stewardship promotes using the right fertilizer source, at the right rate, at the right time, and in the right place. The 4Rs can help increase yields and profitability.

Site-Specific Nutrient Management

Site-specific nutrient management is a component of precision agriculture that allows for fine-tuning crop management systems along with 4R Nutrient Stewardship.
