Are Fertilizer Use Returns Optimal In Kenyan Farms?

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 […]

Integrated Soil Acid Management (ISAM) Approaches For Increased Soil Nitrogen Availability and Productivity

In many places of the world, soil acidity is a substantial constraint to soil productivity. Sodium, aluminum, manganese, and hydrogen ion toxicity, as well as deficits in critical elements such as nitrogen, calcium, magnesium, phosphorus, and molybdenum, all contribute to plant growth suppression. Agricultural management practices have increased shifts in soil pH, raising concerns about […]

The ABC of Cover Crops – Part 2

In my last article, we dealt with the many benefits of cover crops and how they can really help improve soil health, soil structure, nutrient availability (especially phosphorous), and water infiltration and moisture holding capacity. These are some of the most important yield destroyers in African soils. Cover cropping, if done properly can really make […]

International Day of Awareness of Food Loss & Waste, Sep 29th

Today, September 29, is the International Day of Awareness of Food Loss and Waste. On this day, we take the opportunity to raise awareness of practices and innovations that help reduce food loss and waste and build more resilient food systems. Food loss and waste undermine the sustainability of our food systems. When food is lost […]

MRL Changes in EU Legislation On Pesticide Residues – August 2022 Update

In recent months, a number of amendments to the EU 396/2005 Regulation have been published. Some of these changes are already active since April 14 and 28 and May 3, 2022. Regulation EU 2021/476 is an amendment of Annexes II, III and IV to Regulation EU 396/2005; and indicates a change in Maximum Residue Levels […]

The ABC of Cover Crops – Part 1

Cover crops are planted to cover the soil rather than for the sole purpose of being harvested. Commercial cropping and removal of crop residue leaves the soil surface bare until the next crop is planted. Bare soils are very fragile and prone to erosion, capping, heating, and degeneration. Bare soils cause floods and dust storms. […]

The Bountiful Benefits Of Biochar

Biochar is the new buzzword in farming.  What is it?  Biochar is basically ‘charred’ agricultural waste created through slow-burning of organic matter in the absence of oxygen (pyrolysis).  This creates a porous, high carbon, stable material that can be added to the soil to improve soil properties.  The claims for the benefits of biochar are […]

Building The Resilience Of The Soil

Soil is important not just for growing plants and supporting our farmers, but it plays a major function in the health of the planet. Soil provides us with what are known as ecosystem services, essential for global health. The resilience of the soil is its capacity to recover and bounce back after a change of regime […]

Getting To Grips With Downy Mildew In Rose Stems

Downy mildew, Peronospora sparsa, is among the most feared diseases in industrial rose production in the highland tropics. Outbreaks are triggered when the presence of inoculum coincides with high relative humidity (> 85%, > 3-4 hrs), cool temperatures (10-18°C) and free moisture on the leaves persist for four hours or more. Young apical tissue is […]

MRL Changes in EU-Legislation On Pesticide Residues

We hope that you will read this newsletter with great interest. The aim of this newsletter is to keep you updated on the new MRLs for certain pesticides that have recently been published by the EU.  Of emphasis, are the updates on EU- MRLs for Chlorate and Perchlorate in particular. If you have any questions, […]

Floods, Droughts & The Soil

Turning soils into sponges: Opportunities to reduce flood and drought risks You may think that the common factor between drought and flood in many places in Kenya is water, especially lately.  Other than the lack or abundance of rain, the major reason for droughts and floods is the soil’s health status and its inability to […]

Role Of Nutrients In Plant Disease & Pest Management

Plant disease & pest management using chemical pesticides raises serious concerns about food safety, environmental quality and pesticide resistance. These concerns have dictated the need for alternative plant disease & pest Management techniques. In particular, plant nutrients could affect the disease tolerance or resistance of plants to pests and diseases. This is evident in the […]

Solutions To Challenges Facing Agriculture In Kenya

In Kenya, the current population is estimated at 47 million and expected to nearly double to 95 million by 2050. Agriculture in Kenya is a fundamental instrument for sustainable development, poverty eradication, and food security.

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. Not so in the greenhouse, where the climate is much hotter and the soil and plants are working hard all year round. Greenhouse soil temperatures are higher and you need to […]

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. Fertigation Benefits The benefits of drip fertigation to plants are that nutrients are applied directly into the active root zone with […]

Calcium Nitrate Alternatives In Hydroponic & Fertigation Systems

Calcium Nitrate is an inorganic compound with the formula Ca(NO3)2 and is mainly used as a component in fertilizers. In soil and plant nutrition Calcium is King. Calcium Nitrate is the only cheapish non-reactive water soluble calcium fertilizer suitable for drip feeding fertigated crops, so it goes without saying that calcium nitrate is the sovereign of fertilizers.  There are […]

An Introduction To Plant Viruses

Plant viruses are viruses that affect plants. Like all other viruses, plant viruses are obligate intracellular parasites that do not have the molecular machinery to replicate without a host. Plant viruses are pathogenic to higher plants.  They can cause a dramatic decrease in yield, quality and shelf life and even plant death. Plant virus are made up of a strand of nucleic acid (DNA or […]
