From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study.
Damaged soil structure can cause reduced yields which could be compensated by increased fertilization rates, but this would also increase the risk of nutrient
The soil test will also tell you what the pH of your soil is. Over fertilization in the garden, caused by well-intended but automatic feeding, often results in fertilizer burn of plants. Too much fertilizer on plants is a serious problem, more damaging than too little fertilizer in many cases. Can Over Fertilized Garden Be Saved? Over-fertilization (i.e., the application of fertilizer nitrogen (N) in excess of the tree or vine capacity to use it for optimum productivity) is associated with high levels of residual nitrate If you add too much fertilizer to your lawn, then that fertilizer can build up and release too much salt into your lawn. A buildup in salt causes the grass and soil to dry out. This can result in grass which turns yellow or brown and is commonly known as fertilizer burn.

A question that remains to be answered is whether such a fundamental process would still be that important in an over-fertilized world, as the long-term effects of fertilization on N fixation and associated 2017-04-28 · Yield of rice and oilseed rape in response to fertilization.
Nitrogen applied to fields in large amounts over time damages topsoil, resulting in reduced crop yields. Sandy soils are much more prone to soil acidification than are clay soils. Clay soils have an ability to buffer the effects of excess chemical fertilization.
The effect of the different fertilization treatments on rice and oilseed rape yield was significant at each study site (Table 1).In This excess nitrogen and phosphorus can be washed from farm fields and into waterways during rain events and when snow melts, and can also leach through the soil and into groundwater over time. High levels of nitrogen and phosphorus can cause eutrophication of water bodies.
Whether your lawn is looking unhealthy or you're simply trying to maintain its current beauty, proper fertilization should be part of your lawn care game plan. Don't rush out and buy fertilizer just yet—take some time to learn what kind of
