The importance of crop health to sustainable crop production

The productivity of crops relates directly to their health. But what is a healthy crop? A healthy crop is a crop that receives sufficient water, nutrients, and light for photosynthesis. Healthy crops are also void of injuries from biotic or abiotic factors. Such crops, growing under optimal conditions, are less susceptible to pests and diseases…

Soil health in a nutshell

Soil is the upper layer of the earth’s crust, which sustains life. It consists of a mixture of mineral particles, organic material, organisms, and liquids, and has various physical, chemical, biological and morphological properties. It sustains plant life, which in turns sustains the lives of animals and humans on the planet. Since we rely on…

Elements of Agroecology

Guiding the transition to sustainable food and agricultural systems. Today’s food and agricultural systems have succeeded in supplying large volumes of food to global markets. However, high-external input, resource-intensive agricultural systems have caused massive deforestation, water scarcities, biodiversity loss, soil depletion and high levels of greenhouse gas emissions. Despite significant progress in recent times, hunger…

Food and clean water start with soil biodiversity

Although soils are vital for agriculture, biodiversity, and clean water, this below-ground world is often overlooked. The loss of life below the ground due to intensification of agriculture, climate change, erosion, and compaction, among other things, is one of the biggest global threats to soils. Many organisms live in the soil. In fact, about 25% of all biodiversity occur…

What many thinks of as “just dirt” is an incredibly complex mixture of rock-derived minerals, plant-derived organic matter, dissolved nutrients, gases, and a rich food web of interacting organisms. By ploughing and overtilling, we have…
