Effects of biochar and farm yard manure on soil properties and crop growth in an agroforestry system in the Himalaya
Open accessAbstract
Many parts of South Asia are facing agricultural land degradation and reduced productivity while the population continues to grow and demand for food is ever-increasing. This paper presents the results of research specifically focused on application of biochar and Farm Yard Manure (FYM) at 5t/ha and 20t/ha, respectively as an amendment on degraded soil in a coffee agroforestry system of the mid-hills in the Nepal Himalaya. The study showed that there were significant (P<0.05) positive effects on soil chemical properties, crop growth (height) and crop productivity. In particular, the soil pH and SOM increased significantly, while other soil properties were not significantly improved. Also, plant growth increased dramatically with application of biochar, however, crop yields showed only slight increases. It is suggested that biochar applied at low rates along with FYM generally has immediate positive effects on the vegetative growth of plants, however, soil properties and overall crop yields may take a longer time to show improvement.

Gautam et al. (2017) reported increased K+ availability upon biochar addition (5 t ha-1) in silty loam Nepalese soil, with main mechanism being high K content in biochar ash and reduced K leaching.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
