Improving feed energy utlisation: Six years of data in the Tsitsikamma

Reading Time: 3 minutes

Energy is imperative to growth and sustenance of all animals, and plays a major role in the production of milk by a dairy cow.

The hype around soil health

Reading Time: 2 minutes

The challenge for farmers is sieving through all these techniques at their disposal and finding that one technique which they understand and identify with – one which is simple and informative enough for them that they would be able to use the results and implement directed management practices on their farm.

Case study: Cation exchange capacity vs Total exchangeable cations, is this another potayto potahto case?

Reading Time: 4 minutes

The soil’s ability to hold nutrients is very closely associated with yield potential. Soil management practices that aim to improve cation exchange capacity guarantee higher and cost effective production.

The relationship between soil carbon and bulk density

Reading Time: 2 minutes

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.

Water use and irrigation

Water use, irrigation and pasture growth on dairy farms: A case study from Oyster Bay

Reading Time: 5 minutes

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.

Soil carbon: A case study in the Tsitsikamma

Reading Time: 2 minutes

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.

Why carbon footprints on farms

Why carbon footprints on farms?

Reading Time: 2 minutes

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.

Spreading fertiliser

Are you wasting nutrients on your farm?

Reading Time: 2 minutes

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.

Water use efficiency

Better water use efficiency can result in greater profitability

Reading Time: 2 minutes

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.

Succesful farming

Farm for success today and the future

Reading Time: 2 minutes

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.
