Soil fertility is the soils ability to provide essential nutrients in sufficient quantities as required by the plant. A soil that has a high bulk density will not be able to provide nutrients in sufficient quantities, because bulk density influences the soils ability to infiltrate and store water.
It is important that all users of fresh water, the agricultural industry being a significant one, are responsible in ensuring the effective and efficient use of the available water.
Carbon in the soil is stored in an organic (or passive) form and an active form. The difference between the two is that the active carbon form is readily available as a food source for microbes, whereas the organic form replenishes the active form and is not readily available to all groups of microorganisms.
What can farmers learn from a carbon footprint? Why do people want to know what a farms carbon footprint is? How is a carbon footprint even related to climate change? In the blog below I will attempt to answer these questions.
Many nutrients are wasted on dairy farms due to oversupply through inputs from fertilizers and feeds. A great deal of nutrients, and therefore money, can be saved by recording and monitoring what nutrients are removed from the farm and what nutrients are brought onto the farm.
By measuring water use efficiency farmers are made aware of where and how much water they are using on their farm. Through this process farmers can identify areas where efficiency can be improved, therefore helping them to save water.
At Trace & Save we believe in placing integrity to our claims of addressing sustainability on farms. One of the ways we do this is by using the concept of measured agricultural sustainability using the SWAN system.
Two of the prominent aspects of sustainability are long-term profitability and environmental protection. Limiting chemical nitrogen fertiliser use to only what is very necessary contributes to both of these aspects.
Excessive use of chemical nitrogen fertiliser has a negative effect on soil life and soil structure. Yet there still seems to be a trend of farmers wanting, or feeling the need, to apply excessive chemical nitrogen fertiliser to pastures.
Every individual in society is reliant on agriculture for the food they eat. The choices that we, as consumers, make in what we buy, influences the demand which is created for certain products or brands.
