When the pH of soil becomes acidic, it can have detrimental effects on plant health. To increase the pH of soil, a component that contains calcium and/
It can germinate even when the soil temperature is as low as 40°F (4.4°C) and up to 85°F (29°C); a rise in temperature higher than this can significantly reduce the germination rate. This is because too high or low temperatures can cause the seeds to become dormant, a state kno...
However, most interest has been focused on species diversity and very little on forest productivity in spite of the face that a decrease in forest productivity influences not only the species diversity but also the living conditions for many people. Many people seem to believe that the store of...

With the intensification of the greenhouse effect, a series of natural phenomena, such as global warming, are gradually recognized; when the ambient temperature increases to the extent that it causes heat stress in plants, agricultural production will in
Cauliflower grows best in soils rich in organic matters and plenty of calcium. Moist, well-drained soil with a pH between 6.5 and 6.8 is required for optimum growth and to discourage clubroot disease. When to Plant During the fall season, you can directly sow cauliflower seeds in your garden...
A soil test will show if adding lime is required to adjust the pH levels in your soil and what rate this should occur at. Furthermore, testing can show whether your soil has insufficient phosphorus, potassium and calcium content; and indicate any deficiencies which exist in these elements that...
If you haven’t added any compost to your soil, you may want to add abalanced vegetable fertilizerbefore planting. This product will supply the three macronutrients:nitrogen, phosphorus, and potassium. Maintenance Adding mulch around the bases will limit weed growth and decrease the amount of time...
It also hampers the growth of trees, causing nutrients such as calcium and magnesium to dissolve in the soil, while releasing aluminum which keeps trees from absorbing water. How is acid rain formed? Acid rain is the result of a chemical reaction that entails the release of sulfur dioxide ...
decrease in their populations due to competition for food (microbes and organic materials), and spatial and temporal changes in food abundance. Nevertheless, considering the presently available data, the beneficial interactions of earthworms and microflora and fauna appear to far outweigh the potential ...
