File SoilNBalSum.OUT provides a summary of inorganic, organic, and overall N mass balance in a single line per simulation format. When running all DSSAT experiments and treatments, a few imbalances show up. I'm summarizing them here. The imbalances are generally in organic N, except as noted.
- Bambara groundnut - UNSB0301.BGX, all treatments had inorganic N imbalance of 5.5 kg/ha. But the following experiment, UNSB0601.BGX is OK.
- Carinata - UFQU1701.BCX, all treatments had inorganic N imbalance of 6.72 kg/ha. The previous BCX experiments were OK.
- Chia - all CIX expeirments had the same inorganic N imbalance of 14.4 kg/ha.
- Chickpea - All CHX trts had the same value of imbalance of 5.3 kg/ha.
- Peanut - The first two peanut experiments had the same level of imbalance, but then it was zero for the remaining experiments (GHWA and after). GHNY9701.PNX and GHNY9801.PNX, all treatments had imbalance of 5.3 kg/ha.
- Pineapple - all PIX treatments had nearly the same level of imbalance: 10.6 (or 10.61) kg/ha.
- Tanier - all three treatments had imbalance of 8.9 kg/ha.
- Taro - all experiments and treatments had imbalance of 5.3 kg/ha.
Rice experiments had a different pattern. The inorganic N had negative imbalance, while organic N had a nearly equal positive imbalance. The imbalance seems to be directly related to fertilizer rate.
- DTSP8502.RIX – fertilizer 0-188 kg/ha, imbalance 0-0.97 kg/ha
- IRMZ8601.RIX – fertilizer 0-140 kg/ha, imbalance 0-3.4 kg/ha
- IRPL8501.RIX – fertilizer 0-120 kg/ha, imbalance 0-6.3 kg/ha
- PULU0001.RIX – fertilizer is the same for all four trts but imbalance ranges from 0 to 4.2
- All other rice experiments are OK. Is it related to flooding?
All Velvetbean treatments show an overall N imbalance, but the inorganic and organic N balances are OK. This is probably a reporting issue rather than an actual imbalance.
