Other claims from this paper (10)
- Intervention effect Seven tonnes per hectare of farmyard manure increased soil organic carbon from 1.4 to 1.6 percent over eight years.
- Intervention effect Farmyard manure had no effect on rice or wheat yield.
- Intervention effect An application of 34 kg P per ha to the rotation gave an economic yield increase in rice, only in the first four years.
- Intervention effect Phosphorus applied through farmyard manure was not adequate for rice.
- Intervention effect From the third year, green manuring replaced the effect of recommended N, P and K fertilizer in increasing rice yield.
- Intervention effect Green manuring had no effect on wheat yield.
- Intervention effect The recommended fertilizer application increased wheat yield.
- Intervention effect Green manuring increased soil total nitrogen and available potassium levels.
- Intervention effect Green manuring reduced soil base saturation.
- Observation After adjusting for transplanting date, there was no statistical evidence of a yield trend in rice or wheat over the experiment.
