Friday, May 18th, 2012

A trace mineral deficiency can affect yield, disease protection, weed pressure, nodulation, reproduction or chlorophyll density and any of these will impact upon your profitability. Here are some guidelines that may help you in the management of trace mineral nutrition (more…)

pH Awareness Can Boost Profitability

Friday, May 18th, 2012

A pH meter is essential equipment for all growers seeking to build productivity sustainably. Soil pH has a major impact upon nutrient uptake. The ideal soil pH for the majority of crops is 6.4 and at this level your soil will provide maximum nutrition. A low soil pH spells problems with the potential to generate excesses of iron, aluminium and manganese as they are more available in acidic conditions. Low soil pH also can mean poor availability of phosphorus, potassium and calcium and magnesium. These are increasingly expensive inputs so it makes good sense to aim for the ideal soil pH where they perform best. (more…)

Putting the Microbes Behind the Minerals

Thursday, May 10th, 2012

Mineral uptake is facilitated by micro-organisms, whether it takes place in the soil, the gut or the leaf surface. A simple recognition of this fact is a prerequisite if we are seeking to abandon old, unproductive paradigms. It is the belief that “science will look after us” that is at the core of the modus operandi that underlies modern agricultural, veterinary and medical science. Acid/salt fertilisers, rescue chemicals, antibiotics and symptom-treating pharmaceuticals are all part of the product-driven “scientific” approach. The definition of the word “science” involves “adherence to natural laws and principles”. (more…)

Prescription Blends

prescription blendsAt times we get asked the question: How long will my Prescription Blend last in the soil and will I require a blend next year? Unfortunately, there isn’t an easy answer to this question; it is really site specific. What it comes down to is how ‘completely’ the initial blend balances and amends the soil, and how much nutrient is lost each year (i.e., crop removal, leaching losses etc). (more…)
