“We found that modest SI measures (small fertilizer quantities, weeding, and crop rotation) led to moderate yield increases of between a factor of 1.2 and 1.6 and reduced soil carbon loss, but they sometimes caused increased growing-season water limitation effects”

“Off-field residue feeding during the dry-to-wet season transition could further reduce feed deficits and decrease rangeland grazing pressure during the early growing season”
“investigate the effect of the mother stem removal period on the above-ground part of the asparagus stem in the non-heated greenhouse of Jeonnam Agricultural Research & Extension Service”
e1
“it is considered that removing the stem in the period between the yellow leaf and the dead leaf, where the nutrients from above-ground are completely flowed to the underground stumps by the decrease in temperature without disease and insect pest is favorable in the nutrient management”
A preferable management mode for tomato is N 286.88 kg·hm-2 and K2O 286.88 kg hm-2 with irrigation at pF 2.0 (10 kPa) upper and pF 2.49 (30 kPa) lower soil water suction limits.
“the preferable irrigation and fertilization management mode of fertilization amount was N 286.88 kg·hm-2,K2O 286.88 kg hm-2,soil water suction of the irrigation upper limit and lower limit were respective pF 2.0(10 kPa) and pF 2.49(30 kPa)”
e4
“the quality of tomato fruit could improved by the proper increase of the irrigation upper limit and the decrease of the conventional fertilization amount significantly”
Reduced nitrogen was beneficial for nutrient absorption, nitrogen use efficiency and lower soil inorganic nitrogen residue and leaching under combined P and K application.
“Taking‘Chungan 3'cabbage as material,with the open vegetable fields in Yanqing county of this area as the object,six treatments were set up,including the control group without fertilization”
e6
“excess nitrogen fertilizer and improper ratio of phosphorus and potassium was unsuitable for the crops on the absorption of nutrients,leading to large amounts of accumulation of inorganic nitrogen in soil and leaching loss;under combined application of phosphorus and potassium,the reduced nitrogen for treatment was beneficial to the crops on the absorption of nutrients,to improve the nitrogen use efficiency,to reduce…” Show full quote
