Nitrogen application influenced the elephant grass yield growing in tropical conditions. The biomass yield reached 43 Mg ha 1 in the second harvest. The application of 100 kg ha 1 N promoted greater efficiency in the use of N and biomass yield. Thus, this is the recommended dose for ...
根据“Dugongs mainly feed on sea-grass.”可知,此处介绍这种动物在饮食方面的情况,选项C“它们每天能吃四五十公斤的海草。”符合,故选C。 (4)题详解: 根据“If dugongs do not get enough to eat, they may produce fewer young.”以及“People put polluted water into the sea, which is bad for se...
Is nitrogen a macronutrient, a micronutrient, or neither? Explain what its primary function is in plant growth and development. Why is the knowledge of a plant's reproductive system important when choosing a breeding strategy? How might you ...
aAs a bonus, corn gluten meal is an excellent source of nitrogen for existing turf! Note that it should be used on existing lawns. Wait 4-6 weeks before seeding your lawn with new grass. 作为奖金,玉米面筋膳食是氮气的一个优秀来源为现有的草皮! 注意在现有的草坪应该使用它。 Wait 4-6 weeks...
For example, drought-induced increases in tissue H2O2 concentrations might increase plant resistance to pathogens [15], while drought-induced accumulation of amino acids, tissue die-off, or increases in tissue nitrogen (N) content as a result of the rewetting-induced peak in soil N availability ...
determine the effect of adding nitrogen to the soil, he/she will have an experiment group of soil to which he adds the nitrogen and a control group of soil to which he doesn't add anything. He'll compare the results of both groups to see if adding soil affected the growth of gra...
In statistical analyses, we used spectral recovery metrics (Fig.2, Table2) and burn severity (dNBR; Fig.2) along with field measurements: fractional cover estimates (% shrub, % grass, % forb, % juvenile conifer), canopy closure, regeneration density, slope, and aspect (cosine-transformed)....
Although gypsum is often touted to "neutralize" dog urine, it cannot neutralize excess nitrogen. Some dog owners report success with gypsum, but it may simply be that it improves soil drainage, which prevents the urine from collecting near the crowns and roots of the grass plants. How can I...
