Farmers know that everything they do is in a cycle — seasonal cycles to be sure for planting, harvesting and preparing the soil for next year’s crops.

Protecting the water cycle is of utmost importance — clean water for people and our communities, animals and crops. Minimizing runoff from manure and commercial fertilizer that could contaminate local waterways or groundwater is also of critical importance.

Farms also think in terms of the nutrient cycle although they may work with various experts along the way. A farmer may work with a dairy nutritionist to meet specific nutrition requirements for their animal feed, work with a custom operator to safely and effectively haul manure and with an agronomist to be sure that soil health is optimized for plant nutrition and runoff control. Sustainable farmers know these nutrient cycles are intertwined and it’s important to connect with experts in each area for the best results.

For example, take three common nutrients: calcium carbonate, calcium-magnesium carbonate and calcium sulfate. Each has a well-established role of supplying calcium and magnesium to the dairy diet. Let’s take calcium carbonate first as a feed ingredient combined in the total mix ration. After the cow’s body absorbs what she needs, any excess will be excreted and eventually make its way into manure storages.

Powdered calcium carbonate may be combined with bedding material to supplement cow comfort. In its powdered form, it has absorbent qualities and offers some pH adjustment. Powdered calcium carbonate is ideal for mixing with wood or other paper by-products for comfortable bedding. Manure from this type of bedding system can be even more beneficial where some calcium is needed in the field as well as some pH adjustment.

Separately, depending on soil needs and crop planning, farms may add calcium carbonate (aglime) directly to their soils prior to planting or in between cutting. Lastly, crops will uptake calcium into the plant, increasing the calcium delivered to the animal and provide the calcium-needed nutrients that are being directly fed.

Calcium-magnesium carbonate offers similar benefits with the advantage of providing a magnesium source to the diet as an essential element. Calcium sulfate offers both calcium and sulfur without pH adjustment as well as other beneficial properties to increase air and water flow in soils.

Farmers know an essential element for growth is high-quality feed and soil health. Farmers who are focused on becoming more sustainable embrace the nutrient cycle for all that it has to offer from feed, manure, soil health and optimal crop nutrition.
