potential fertility of soil

基本解釋

Taking Kai County as an example, a method of comprehensive evaluation of soil fertility level and the estimation of potential productivity is proposed and discussed.
以四川開(kāi)縣為例，探討了土壤肥力的綜合評(píng)價(jià)及土壤增產(chǎn)潛力的估算方法。
The study shows that big difference exists with the highest potential yield permitted by soil fertility under the condition of modern method of high-yielding fertilizer application.
研究表明，盡管作物施肥存在最小因子優(yōu)勢(shì)效應(yīng)，但它與現(xiàn)代高產(chǎn)施肥獲得地力潛在最高產(chǎn)量還具有本質(zhì)的區(qū)別。
The analytical data revealed that the potential fertility of the dryland soils was rather low, such as nitrogen, phosphorus and potassium content in soil were deficient on the whole.
分析數(shù)據(jù)表明，該區(qū)旱地土壤潛在肥力較低，有機(jī)質(zhì)含量差異較大，大部分土壤氮、磷、鉀養(yǎng)分供應(yīng)不足。
