Is Fall Armyworm Falling Away?

Think Agronomy 15th May 2020 If you set out to collect several hundred Fall Armyworm larvae for an experiment, I can tell you that it is a long task, which seems to take longer each year. Sure, if you look for them they are easy enough to find in fields that have perhaps not received […]

Soil Preparation For Maize, Wheat & Barley Production

Soil or land preparation for farming is foundational when growing cereals like maize wheat and barley. In this article we’ll explore the key critical soil requirements for cereal production namely: soil sampling, soil preparation and planting & Deep Nitrogen Testing Soil Sampling Why soil sampling improves profitability How to sample properly Grid vs zone sampling […]

Maize Plant Populations

Maize plant population and seed rate comparison data from our maize variety trial sites has been very enlightening. Last week we looked at the results of our Cropnuts Maize Variety Trials in 2019 and highlighted how some maize varieties perform very differently at higher plant populations. Within the Variety Trials last year at every site, […]

Plant Nutrition Basics In Floriculture

Plant nutrition is the study of the chemical elements and compounds necessary for plant growth, plant metabolism and their external supply. Without proper plant nutrition, plants tend to die off or produce little or no yield. In my line of work I visit hundreds of flower farms a year; the flourishing, the ticking over, and the ones in […]

Greenhouse Soil Tips For Beginners

Greenhouse soil crops need more specialized care. When you grow plants out in the open field, your soil has time to rest and regenerate.

Latest Insights From Our Crop Field Trials

Importance of Molybdenum & Cobalt On Legumes Looking back through some of our legume crop field trials which have focused mainly on peas, the use of molybdenum and cobalt on the seed has consistently shown improvements in nodulation and yield. We know how important molybdenum is on legumes and brassicas in most Kenyan soils so […]

Coffee Nutrient Requirements

Two big yield limitations in coffee are: low soil pH Micronutrient deficiencies Years of applying acidic fertilizers in conjunction with leaching have caused many soils in coffee growing areas in Kenya to become very acidic.  Low soil pH affects the crop in two ways:- Reduced Fertilizer Efficiency At low pH, fertilizers like Phosphorous (P) get bound […]

High Sodium Soil Effect On Plant Growth

In Africa, and especially in Kenya, high sodium soil is one of the major causes of yield losses, quality reduction and crop failure in irrigated agriculture.  So today, in our first newsletter, we are going to talk about sodium in the soil. The Effect Of Soil Sodium Soils with a high percentage of sodium in […]

How Organic Matter Creates Sustainable, Carbon-Friendly Agriculture

Soil organic matter (SOM) is the organic matter component of soil, consisting of plant and animal remains at various stages of decomposition, cells and tissues of soil microbes, and substances that soil microbes synthesize (Wikipedia). In order to save the world from self-destruction, we need to move towards sustainable carbon friendly farming. Many farms in Kenya have already embarked on this journey. […]

Designing A Suitable Fertigation System

Fertigation is the application of fertilizer together with the irrigation water. The most common form of fertigation in Kenya is via drip irrigation. Fertigation provides precise nutrition, application flexibility, minimized loses & environmental protection.
