...含量超過10%，而本港農地平均只有3.4%左右。多施堆肥就可以改善這方面的情況。 2. 含氮量不低於0.2%，含磷量(P2O5)不低於20 ppm，含鉀量 (K2O)不低於200 ppm。根據本署最近的土壤普查結果，本港農地普遍缺鉀，農友要多增鉀肥，才能有好的收成。 3. 酸鹼度接近中性，疏水透氣性能良好。使用化肥不當，例如，長期使用硫酸銨，土壤會很容易變酸。另外，植物的根往往也會分泌有機酸，所以，長期耕種的土壤通常呈酸性。過酸或過鹼都會影響植物對營養的吸收，所以，土壤偏酸時，要用熟石灰來中和，偏鹼時，用石膏（硫酸鈣）來中和。 要使土壤肥力得到維持，採用以下的耕作方法是個好主意： 1. 作物品種...
