ORGANIC TOXINS: ‘SUFFOCATING’ OUR SOILS

Among the contaminants of concern, organic pollutants occupy a unique place because they bind and hold onto organic matter in our soils over long periods of time. Some more potent ones like aflatoxins and dioxins also easily find their way into the food chain endangering the lives of many. But why should such pollutants matter?… Continue reading ORGANIC TOXINS: ‘SUFFOCATING’ OUR SOILS

CONTAMINATED SOILS: HALTING THE METALLIC INVASION

Metals can neither be created, destroyed nor degraded. Yet some of them are not only notorious soil pollutants but also easily taken up by food crops leading to communal exposure through the food chain. Though some metals like calcium, potassium, iron, manganese, magnesium and zinc are valuable in metabolic processes, others especially the heavy metal… Continue reading CONTAMINATED SOILS: HALTING THE METALLIC INVASION

SEWAGE: FROM WASTEWATER TO FOOD

Food delights us because it tastes good. But our interest must go beyond just mere taste... We must be concerned with how it's grown. SEWAGE It's hard to imagine how such a repulsive body of water could facilitate growth of the vegetables served on our dinner tables. But this is precisely the case. Sewage effluents… Continue reading SEWAGE: FROM WASTEWATER TO FOOD

CADMIUM POLLUTION: QUESTIONS BEGGING ANSWERS

Cadmium pollution raises more questions than answers because of three reasons: Firstly, cadmium is very scarce on the earth's crust. Why is it increasingly gaining notoriety as a metal pollutant? Secondly, unlike many other metallic pollutants, cadmium is highly toxic even at very small doses. Why aren't stringent measures being put in place to monitor… Continue reading CADMIUM POLLUTION: QUESTIONS BEGGING ANSWERS

VERSATILE BIOCHAR: FUEL BEYOND FERTILIZER

Rarely do we come across an end product who's production process is also filled with immense benefit. Biochar is one such kind of material. Whereas biochar production could be done in a sophisticated manner using an inert atmosphere oven, the costs are prohibitive for most rural households. Simple innovations have however made it possible not… Continue reading VERSATILE BIOCHAR: FUEL BEYOND FERTILIZER

VERSATILE BIOCHAR: CONVERTING POLLUTANTS INTO FERTILIZERS

Every time I used to walk past a green colored waterbody, I would write it off as waste. But not now. Green water results from the excessive presence of phosphates and nitrates from fertilizer runoffs and wastewater. These two pollutants boost the development of algae and vascular plants such as hyacinths which feed on the… Continue reading VERSATILE BIOCHAR: CONVERTING POLLUTANTS INTO FERTILIZERS

VERSATILE BIOCHAR: REJUVENATING OUR SOILS

Our soils feed us. However these same soils experience a depletion of nutrients without replenishment over time. Also many agricultural soils have a reduced microbial life, a low water holding capacity and extreme pH levels. The results are poor yields every year threatening food security for future generations. Soil amendments such as biochar are designed… Continue reading VERSATILE BIOCHAR: REJUVENATING OUR SOILS
