However, in the simulation, we found that the equilibrium between growing radicals and nitroxyl radicals was a CPU-intensive and time-consuming process, therefore, a hybrid algorithm with an analytical expression for the exchange equilibrium and with a biased sampling technique for those elementary reactions of small probabilities was used to improve the stochastic algorithm.

Within a short time span of just over 40 years China has developed from an insignificant to the world's largest and still fastest growing producer and user of chemical nitrogen fertilizer. Unfortunately China is now also the country with the most unbalanced nutrient ratio. If continued into the future, the grave nutrient imbalance that prevails at present threatens the fertility of China's soils that has been maintained so well over the centuries, thereby also threatening, sustainable agriculture.

The average level of the soil available potassium was 119.96 mg/kg, which decreased 18.94 mg/kg and 1.05 mg/kg one year averagely. But the decreasing trend alleviated in recent years. There were 39.5 kg/hm^2 nitrogen and 30.9 kg/hm^2 phosphorus (P2O5) more than needed averagely, and 150.0 kg/hm^2 potassium (K2O) in deficiency. Though the fertilizer application was high and the rate of fertilizer was 647.96 kg/hm^2 in nutrient, the ratio of organic to inorganic was still unreasonable. The ratio of the chemical fertilizer nitrogen phosphorus (P2O5) and potassium (K2O) was 1:0.42:0.14. The nitrogen application was enough and even higher than that was needed. The phosphorus was proper elementarily and potassium was in deficiency. The yield of wheat which was the main crop increased slightly and that of other autumn harvest crops was stable.
