“…Our results do not provide evidence for a significant effect of mineral NPK on C tot content in soil. Some researches indicate that the application of organic manure in combination with inorganic fertilizer linearly increased soil organic C levels (Böhme et al 2005, Li et al 2010. In the present experiment, the addition of mineral NPK fertilizers to compost and cattle slurry with straw increased the C tot content in the soil (by about 7%) but the same addition to FYM was ineffective.…”

This study assesses the effect of long-term (59 years) application of organic and inorganic fertilizers on soil organic matter and enzyme activity. Total organic C, total organic N, hot water soluble C, microbial biomass C and dehydrogenase activity were evaluated in soil from the long-term field experiment in Prague-Ruzyně (Orthic Luvisol, clay loam). Total organic C and N increased significantly in soils treated with organic fertilizers (farmyard manure, compost) and in soils with a combination of organic and mineral NPK fertilizers (manure + NPK, compost + NPK, cattle manure + straw + NPK) compared to soil treated with inorganic fertilizer, cattle slurry + straw and non-fertilized control. Farmyard manure significantly increased hot water soluble C compared to the control. Dehydrogenase activity was significantly increased by all treatments compared to control. The results indicate that additions of organic matter from various sources differ in the effects on soil organic matter and biological activity. The effect of manure was the most favourable; long-term application of cattle slurry + straw is rather similar to mineral fertilization.

“…Apparently, application of only fertilizers did not increase SOC content over long-term cropping. This observation was consistent with that of Rudrappa et al, (2005), Gong et al, (2009), Li et al, (2010 who recorded increase in carbon fractions under organic treatment which was attributed to the availability of additional mineralisable and readily hydrolysable carbon resulting in higher microbial activity (Chan et al, 2001). The inclusion of legumes in cropping systems had beneficial effect on carbon distribution of different soil carbon pools.…”

“…The grain yields of rice and wheat were significantly greater with the application of 50% mineral NPK fertilizer supplemented with 50% N through FYM (T 6 ) as compared to the recommended level of NPK fertiliser (T 5 ), whereas straw yields of both crops were similar under combined application of manure with sub-optimal doses (below 100% of fertiliser NPK). The results revealed that balanced fertilisation improves the grain yield (Gu et al 2009, Li et al 2010. Balance nutrition facilitates the translocation of nutrients to the economic part of the crop (Yang et al 2004); the residual effect of organic manures applied to rice on the grain yield of succeeding wheat was statistically significant (Bi et al 2009); but the straw yield was found to be non significant.…”

We measured the long-term (28 years) sustainability of rice-wheat cropping system under integrated nutrient management practices emphasizing the trends in grain yields, sustainable yield index (SYI) and nutrient budgeting. The data of long-term experiment revealed that grain yield of both rice and wheat declined under control and sub-optimal fertilizer inputs (50% or 75% recommended fertilizer NPK). Negative yield trend (slope) was observed in control plots for rice (-0.0296) and wheat (-0.0070); whereas positive yield trend was observed under treatments receiving organic supplements. The SYI values indicate that rice yields are more sustainable than wheat. Data on apparent nutrient balance showed a deficit of N (-42.2 kg/ha/year), P (-9.1 kg/ha/year) and K (-52.2 kg/ha/year) under control plots. Surprisingly, there was net depletion of K under the organic supplemented plots. Correlation study revealed that apparent balance of K was negatively correlated with SYI (r = -0.921 for rice; r = -0.914 for wheat) and yield slope (r = -0.870 for rice; r = -0.896 for wheat). If the trend of K imbalance is not reversed, the potential to improve N and P fertilizer use efficiency and crop yields will be limited.
