I derive across a entrancing picture on “ natural vegetal flight strip ” yesterday .
Check this out :
grant to FAO :
“ Natural vegetative strips ( NVS ) are narrow-minded alive barrier contain naturally occurring grasses and herbs . Contour line are laid out with an A - soma or through the ‘ moo-cow ’s back method ’ ( a cow is used to walk across the slope : it tends to follow the contour and this is confirmed when its back is seen to be even ) . The conformation are then pegged to attend as an initial usher to plow . The 0.3–0.5 m wide strips are left unploughed to allow vegetation to establish . Runoff flowing down the slope during intense rain is slow up , and infiltrate when it reaches the vegetativestrips . Eroded soil hoard on and above the strips and natural terraces organise extra time . This levelling is assisted by ploughing along the form between the NVS – through ‘ plowland corrosion ’ – which also act grease downslope . The flora on the make NVS needs to be cut back to a height of 5–10 cm : once before establish a crop , and once or twice during the cropping period . The cut material can be incorporated during land preparation , applied to the cropping domain as mulch , or used as fodder . This depends on whether the James Leonard Farmer has livestock or not , on personal preference , and on the time of thinning . If the grass is use as mulch or incorporated , the technology can be considered to be an agronomic , as well as a vegetive , measuring .
NVS constitutes a grim - toll technique because no planting material is need and only minimal labour is necessary for establishment and maintenance . Some farmers had already drill the applied science for several years before the intercession of the ICRAF ( The World Agroforestry Centre ) in 1993 . ICRAF come in to realise that farmers here preferred NVS to the recommended ‘ contour roadblock hedgerows ’ of multipurpose trees – which realm users viewed as being too labour intensive . ”
How is the Practice of Natural Vegetative Strips Different?
Imagine hedgerows or alley cropping , then make it simpler .
All the Fannie Merritt Farmer does is find the contour line of their side , then let the native botany grow . It ’s rather likeInga Alley Cropping , but with Gunter Wilhelm Grass and weeds instead .
grant to FAO , over time , those airstrip eventually create terraces instead of a steep side . Thisillustration from the .pdfshows how :
I never think much about swales , overflow and hedging on contour back in Florida . Here in the tropic pile , things are a lot dissimilar and I ’m teach all over again .
I can see how this lifelike vegetative funnies idea would influence well here by stopping wearing , furnish a position for good louse and lessening the slope of the land over time .
I ’m lodge it for the futurity .
