Human nature being what it is, a degree of nervousness about the amount of growth over the coming summer is to be expected, however past growth records combined with the digging of a few holes will help with feed budgeting. Here in the Rotorua district the December...

Dairy cows are amazingly tough and resilient animals with the majority remaining outdoors all year. Diets vary widely; most survive through harsh winter and early spring conditions, give birth, and produce remarkably well. Some years ago a farmer in the Waikato...

Dolomite because it typically contains 24% calcium and 11.5% magnesium, both in the carbonate form, has a liming (pH modifying) effect when applied to soil. As a result beneficial soil life is stimulated. It is very difficult to measure beneficial soil microbes as we...

The rule is simple, feed magnesium to cows prior to calving and calcium after, or is it? We grew up with the knowledge that feeding magnesium prior to calving helped with the release of calcium from the animals own reserves. As cows got older and bones hardened...
