Crop Nutrients – Improving Quality and Productivity of your Soil
Plant nutrition plays a very important role in determining a successful crop. Dakota AGrow helps growers improve both the quality and productivity of their soil through increased fertility in all types of situations.
Crop nutrients. Nitrogen (N), phosphorous (P), and potassium (K) are the three main nutrients that are conventionally supplied by inorganic fertilizers. Nutrients may also be supplied by other products and processes such as organic manures, plants residues, and biological nitrogen fixation. Nutrient management is critical in order to increase or maintain crop yields on a single parcel of agricultural land. To meet crop needs throughout a growing season soil fertility must be consistently high. There are fourteen nutrients that are supplied to crops from soil and fertilizer sources. Of these, 6 are generally considered macronutrients, while the rest are micronutrients. Macronutrients are used in relatively larger amounts by the plant, however micronutrient deficiencies can be equally damaging to yield and profitability.
We provide a consulting service specifically dealing with soil fertility and problems that are closely related. The principal goal is to help those who use the services we offer to economically achieve an ideal level of productivity and quality in terms of the soil and the crops grown on each soil. Our work involves utilizing specific soil tests and plant tests to determine nutrient needs, and recommend the appropriate types and amounts of fertilizers and soil amendments to fill those needs.

- Soil testing is a useful and relatively inexpensive management tool for growers to assess crop nutrient levels in their fields.
- Proper methods and timing of soil sampling help ensure reliability of test results for making informed decisions related to soil inputs such as fertilizer and lime.
- Standard soil tests typically evaluate pH, buffer pH, organic matter, cation exchange capacity, phosphorus, potassium, calcium, magnesium and base saturation.
- Micronutrient soil testing alone is generally not a reliable tool to predict potential micronutrient deficiencies. Tissue testing, soil properties, and growing conditions together are a more complete diagnostic approach.
- Critical levels of nutrients (the point below which crop yield may decrease quickly) and crop removal rates are useful for determining the rate and frequency of fertilizer application to a field.
Growers must efficiently manage field inputs while reducing the risk of yield losses to maximize profitability season after season. Fertilizers are significant variable costs in production, and tools are available to assess their need. This Crop Insights will describe best management practices for soil testing, report interpretation, and assessing fertilizer needs for crops in North America.
IS PLANT SAMPLING IMPORTANT?
YES, it has been estimated that 20-30% of your crops potential yield is lost due to fertilizer deficiencies. A good plant sampling program could detect these deficiencies early enough to correct the problem and alleviate the yield loss.
WHEN DO YOU NEED TO PULL PLANT SAMPLES?
Plants can be sampled and analyzed any time during the growing season. However, it is recommended that sampling occur early in the growth cycle. Ideally, plants should be sampled at the early or vegetative stage and at the mid-point or early fruiting stage. If any nutritional deficiencies occur at these stages corrections can be made without any great loss of yield.
