Evaluating Performance of Ecologically Sound Organic Substrates under Different Temperature Regimes
SHAHIDUL ISLAM, U Arkansas, INTERNATIONAL JOURNAL OF AGRICULTURE & BIOLOGY, 2008

ABSTRACT
Greenhouse trials were carried out over two years to investigate the high temperature (25ºC, 30ºC & 35ºC) effects on ecologically sound untreated organic substrates viz., coconut coir and rice husk charcoal, in comparison to that of rock wool using tomato (Lycopersicon esculentum Miller) as a test crop. There were no significant differences in the root dry matter, stem dry matter, fruit dry matter, shoot and root ratio, ascorbic acid, total soluble solid, fruit acidity, leaf chlorophyll contents and pH of the fruit homogenate. Among the substrates, water holding capacity was larger in rock wool followed by coconut coir and rice husk charcoal. Bulk density and total pore space were lower in rice husk charcoal than coconut coir and rock wool. Regarding the chemical properties, rice husk charcoal and coconut coir had higher EC values compared to rock wool. Rice husk charcoal had relatively higher pH followed by rock wool and coconut coir. In the case of CEC rook wool showed significantly higher values than coconut coir and rice husk charcoal. It also appeared that rice husk charcoal and coconut coir gave similar and/or better crop performance and yield of tomatoes than rock wool under high temperature stress conditions namely 30oC and 35ºC as compared with 25ºC. Thus, rice husk charcoal and coconut coir can be used successfully as growing media amendments for producing greenhouse tomato as well as other nursery crops.

Black is the New Green: SHI Field Staff Learn the Benefits of Biochar for Agriculture

During the annual Board and staff meeting held in January in Honduras, field staff from Honduras, Nicaragua, Belize and Panama attended a workshop presented by Julie Major of Cornell University on managing soils with biochar. Biochar can be made simply and cheaply from any organic material, just by piling it, covering it up with soil to exclude air and setting it on fire. During the workshop biochar was made from rice hulls and pieces of pine wood for demonstration, but any crop residue or plant waste can be used to make biochar, such as coffee pulp, sawdust, sugarcane bagasse, etc.

I just got to visit my biochar trial at BIOTROP today so I took a few photos to give all you some idea of the profound difference biochar makes to subsoil

What we're seeing is the plants treated with VAM fungi + biochar are a lot darker green and show more plant growth at the 75day mark so I'll push on up to day90 and see what happens.

This is a small trial I'm doing for some farmers just outside Hangzhou to show them the benefits of Biochar. I've 48 plots in all so 24 with rice husk charcoal addition at 20Kg per plot. This trial is not for scientific data collection we have that in another trial a little further outside town.
