Beneficial soil microorganisms can suppress soil-borne plant diseases through various mechanisms: Antagonism: Some soil microbes act as natural antagonists to plant pathogens. They produce antimicrobial compounds that inhibit the growth and activity of harmful microorganisms. This biocontrol mechanism reduces the incidence and severity of diseases. Competition for Resources: Beneficial microbes compete with pathogens for space […]

Every time I attend a talk, watch a video, or read an article on crop nutrition, the moment I hear the words “Nutrient X is important for [pollen formation / photosynthesis / insert any other process in the plant]”, I switch off. Whilst it is entirely true that different nutrients perform very different functions within […]

Cash flow, an opportunity to make a bit of profit, improve the soil, and to try out new crops in a lower-risk situation. It may seem a long way off, but these are the reasons why some of the very progressive farmers I work with use off-season crops after maize or wheat. For most farmers […]

For five years we have tested maize plant populations, and every year we find that the existing advice to plant at 45-50,000 plants/ha does not produce the highest yields or the highest margin – or the best weed control. It is very clear that maize plant populations across the country need a fundamental re-think, and […]

I hope this article finds you well. As we wind up on the planting of the irrigated wheat crops, I wanted to highlight the significance of leaf sampling for maximizing our crop performance and share valuable insights on this essential practice. Leaf sampling is a valuable tool for irrigated wheat production, enabling growers to assess […]

Maize silage Easy to establish and reliable, maize produces a very palatable and high-energy silage provided that it is well chopped and ensiled properly. Typically over 11 Mj of metabolisable energy per kilo, it is a great way of storing crop to feed for livestock later. The main drawbacks are that it needs to be […]

A good crop begins with putting the seed in the ground well, into a good growing environment. This means a well-structured soil with plenty of oxygen so that the roots can explore and grow rapidly in length and access as much soil volume as possible. In turn, this allows the growing crop to access more […]

Background information While many approaches, such as nutrient omission trials, have been shown to be beneficial in adjusting fertilizer recommendations such as nitrogen (N) fertilizer-based rates, severe nitrogen deficiencies persist across Kenyan farms. These can be attributed under application of N, or N loss. A large amount of the applied N is lost due to […]
