Abstract
A method for applying liquid plastic polymers to soil surfaces in order to form a continuous membrane film for soil mulch. The plastic mulch is useful for enhancing crop production, disinfestation of soil by solarization and prevention of soil erosion. Additionally, the invention includes procedures for applying and spraying the liquid plastic polymers to form an effective and economic film.
Claims20
A method for applying plastic coats on soil comprising:
- a) smoothing and saturating the soil surface, b) coating said soil with plastic coats by spraying an appropriate polymer formulation for forming said plastic coats on said soil by use of spraying means, wherein the polymer formulation is applied in at least two coats, first a primer coat consisting of a diluted formulation of up to 8% by weight polymer and successively at least one other main coat consisting of up to 40% by weight polymer, the at least two coats forming a film having a coat weight of not more than 30 g/m2.

- wherein the spraying means are comprised of a sprayer unit consisting of a boom whose spraying lines are mounted with flat fan nozzles placed at short distances apart;
- and wherein the application of the at least two coats is by applying the spray in two passes or in a single pass using said spraying means having a triple tank and boom system, each tank having its own boom, wherein one tank is used for the primer coat, one tank is used for the main coat and one tank is used for rinsing the sprayer.
