PROTECT THE SEEDLINGSWhile sowing, the farmer should consider the germination percentage and succession rate of 20 per cent hence should plant in the seedbed 108,000 seeds equivalent to approximately half-a-kilo.The seeds should then be covered lightly and mulching done to prevent splash erosion
In all, the effects of vetiver grass roots on erosion control and mass movement can be summarized as follows: (1) preventing surface erosion through the soil-binding properties of roots, (2) reducing effects of splash erosion
through rainfall interception of vegetation canopy, (3) reducing the incidence of shallow slope instability through the anchoring properties of roots, (4) channeling run-off to alter slope hydrology, and (5) providing support to the base of the slope and trapping material moving down the slope.
Hence on site 1 the erosion problems were identified as rill, interill and splash erosion
. Another problem of this site is the steep slope (55%) (See Table 1).
Assessment of sediment yield by splash erosion
on a semi-arid soil with varying cryptogam cover.
, sheet erosion, rill erosion, and gully erosion are all types of water erosion.
Experimental work has also demonstrated that values of the tillage flux coefficient ([k.sub.f]) for a single mouldboard tillage operation are of the order of 200-300 kg/m, which is an order of magnitude larger than for other diffusive processes such as soil creep and splash erosion
(Govers et al.
* Splash erosion
is the direct movement of soil by splashing.
Good agreement was observed with diffusive redistribution, which included splash erosion
, soil creep, and tillage.
While carrying out management practices such as weeding and pruning, one should use disinfected tools and work from areas that are not affected to avoid further spread of the disease.During the rainy season, splash erosion
also causes the spread of diseases as the spores are easily dispersed.
Investigations were conducted into the effects of Agri-SC treatments on splash erosion
, whereas other commercially-available soil conditioners, including "Humus," "SoilTex," and "Kiwi Green," were incorporated in a comparative study of effects on crust strength, bulk density, and aggregate stability.
. Some observations on the splash cup technique.
Another possible check is to split the models into smaller sub-models (Bunnel 1989), such as a hydrologic model and an erosion model, or even the splash erosion
and flow erosion components.
