Biochar: Effects on Crop Productivity and Soil Properties
World food security is under challenge to a great extent due to effects of climate change, continued population growth and resource-depleting practices on agriculture (IAASTD, 2009). Presently poor farmers use either organic manure or inorganic fertilizers (Mando et al., 2005; Topoliantz et al., 2005) for maintaining soil fertility as they cannot afford to apply fertilizers as a nutrient source...
متن کاملCommercial scale agricultural biochar field trial in Québec, Canada over two years: effects of biochar on soil fertility, biology and crop productivity and quality
A commercial scale biochar field trial was established on a farm in Québec, Canada in May 2008. A very fine, commercially available biochar from fast pyrolysis of wood waste was applied as received from the manufacturer using standard farm machinery. The target application rate was 5.6 t/ha, but an estimated 30% of the material was wind-blown and lost during handling, transport to the field, so...
متن کاملTillage Effects on Soil Health and Crop Productivity: A Review
The cultivation of agricultural soils has until recently predominantly been achieved by inverting the soil using tools such as the plough. Soil tillage is one of the basic and important components of agricultural production technology. Various forms of tillage are practised throughout the world, ranging from the use of simple stick or jab to the sophisticated para-plough. The practices develope...
متن کاملAccounting for soil biotic effects on soil health and crop productivity in the design of crop rotations.
There is an urgent need for novel agronomic improvements capable of boosting crop yields while alleviating environmental impacts. One such approach is the use of optimized crop rotations. However, a set of measurements that can serve as guiding principles for the design of crop rotations is lacking. Crop rotations take advantage of niche complementarity, enabling the optimization of nutrient us...
متن کاملSoil Physical Properties and Crop Productivity of an Eroded Soil Amended with Cattle Manure
Erosion changes soil properties, especially physical properties, mainly because it removes surface soil rich in organic materials and exposes lower soil layers. In 1988, a study was established to determine the effects of soil erosion and long-term manure applications on selected soil phys ical properties and corn (Zea mays L.) production. After 10 years of an nual manure applications, soil c...
