The potassium paradox: Implications for soil fertility, crop production and human health

In the chemical age of agriculture that began in the 1960s, potassium chloride (KCl), the common salt often referred to as potash, has and is widely used as a major fertiliser in the Corn Belt without regard to the huge soil reserves that were once recognized for their fundamental importance to soil fertility.

Fish and chips straight from the backyard

What is Aquaponics? If you’re looking for the next step up in food production, Aquaponics could be perfect. Aquaponics is a “discipline” that has evolved from taking the best of aquaculture and the best of hydroponics.  Where aquaculture only grows fish,  and, hydroponics — plants,   Aquaponics is a natural system that grows fish and plants, […]

Permaculture – a renaissance

Much of the language has changed but not the principles.  If one was to devote and indeed preserve an environment through permaculture — a framework for a sustainable agricultural system, devised by Aussies, Bill Mollison and David Holmgren, you would discover a simple rule, harmony with nature.  Modern term, sustainability. It all sounded so posh […]

Manures fight fungus – alternative to chemical control

Researchers at the Basque Institute for Agricultural Research and Development, Neiker-Tecnalia, have confirmed that the use of semi-composted manure in combination with the plastic sealing of the soil is an effective control for Phytophthora capsici, a fungus responsible for a disease that seriously affects greenhouse-grown peppers. The research developed in the PhD thesis by the […]

Stop abusing insecticides in rice

To prevent devastating insect pest outbreaks in rice that cause millions of dollars of damage, the International Rice Research Institute has called for a ban on certain insecticides in rice production. To prevent devastating insect pest outbreaks in rice that cause millions of dollars of damage, the International Rice Research Institute (IRRI) has called for […]
