The present invention relates to a method for regulating the pH of a soil as well as the use of at least one earth alkali carbonate-containing material having a weight median particle size d.sub.50 value of ≤50.0 μm for optimizing or improving the pH of a soil as well as the use of an irrigation or spraying system for the application of an aqueous suspension comprising at least one earth alkali carbonate-containing material in order to optimize or improve the pH of a soil.

A hillside agricultural irrigation apparatus includes an agricultural irrigation pipe extending across a slope of hillside in a direction that is transverse to the slope, and braces coupled between the agricultural irrigation pipe and the hillside for disabling the agricultural irrigation pipe from sliding or rolling down the hillside, the braces are spaced apart longitudinally along the agricultural irrigation pipe and each includes a collar on the agricultural irrigation pipe, and at least one anchor coupled between the collar and the hillside anchoring the collar to the hillside disabling the agricultural irrigation pipe from sliding or rolling down the hillside.

The invention relates to a method and terminal equipment for planting vegetables on internet rental land, thereby enabling land lessees with idle land to cooperate with urban people seeking to eat green vegetables which are economical and practical, on the one hand, meeting the requirement that urban people eat green vegetables which are practical and reliable, on the other hand, enabling idle land to be reasonably utilized, especially wasting land in rural areas, and bringing considerable benefits to the land lessees; meanwhile, along with the popularization and application of the method and the terminal equipment, a large number of employment posts can be brought to rural areas, and the economic development of the rural areas can be promoted.

A sprinkler head protector is a cylinder with a sleeve-style base having two differently configured caps. The first cap is a flat cap with a center hole. The second cap is a two-part split cap in the overall shape of a donut. A center opening in the first and second cap allows a sprinkler head to smoothly extend through the opening. Should repair or replacement of the sprinkler head be desired, either cap is removed thereby facilitating replacement of the sprinkler head.
