Estimating the term…
An agent for the prevention of salt damage of plants for use in intermediate soil comprised of water-repellent particles, and a method of preventing salt damage to plants from salty soil using an agent to establish a water-repellent layer as a layer above the underground water level. An agent for the prevention of salt accumulation in greenhouse soil comprised of hydrophobic particles which are substantially hydrophobic. A salt accumulation prevention layer containing an agent for the prevention of salt accumulation in greenhouse soil which is provided at the surface layer or a prescribed depth from the surface layer of the greenhouse soil.
A method of preventing salt and metal damage to plants which comprises forming a discrete water-repellent layer above an underground water level and wherein said water-repellant layer is lower than the level of plant roots, said water-repellant layer consisting essentially of hydrophobic particles and being 0.5-500 mm thick.
A method of producing plants which comprises cultivating plants in soil having a discrete water-repellant layer above an underground water level and wherein said water-repellant layer is lower than the level of plant roots, said water-repellant layer consisting essentially of hydrophobic particles and being 0.5-500 mm thick.
A method of preventing salt and metal ion accumulation in greenhouse soil which comprises providing a discrete salt and metal ion accumulation protection layer consisting essentially of hydrophobic particles which are below a surface layer of soil, said protection layer being 0.5-500 mm thick.
A method of preventing salt and metal ion accumulation in greenhouse soil which comprises providing a discrete salt and metal ion accumulation protection layer consisting essentially of hydrophobic particles which are a surface layer of soil, said particle layer being 0.5-500 mm thick.
