If anyone is in doubt as to the need for better management of our pasture lands then this short video will allay those doubts. See the difference in the absorbability of grassland managed with time-based feeding with long, full recovery of the grasses before being grazed again.
1 inch of water takes 10 seconds to infiltrate the soil.
Compare this with the soil of the grassland, just over the fence, managed with season-long grazing.
1 inch of water takes 7 minutes and 3 seconds to infiltrate the soil.
After nine months of cropping, just next to this, even though the soil was not worked, it has further compacted and lost its ability to infiltrate the rain falling on it remarkably.
1 inch of water takes 31 minutes and 13 seconds.
Each inch of water shed as run-off loses 150 to 200 Lbs of grass production along with loss of nutrients from the soil and loss of soil though erosion.
They say “Seeing is believing”: watch this short video and believe!
Grassland Soil Health: Infiltration http://youtu.be/i_JOTeMg7Cw

When the rain comes, will your soil be ready? Management of grasslands is paramount to the health of our soil and water resources. Recently, conservationists with the Natural Resources Conservation Service (NRCS) in South Dakota have been studying the effects that management has on soil properties, such as infiltration, and the results are dramatic. Studies like these show that infiltration is significantly impacted by the management practices being implemented on the land.
Increased infiltration resulting from better management means that the water that falls on an operation will benefit that operation. Changes in management don’t have to be drastic to have a positive influence on infiltration and ultimately the health of your natural resources and your bottom line.

The Savory Institute have addressed that very need of scientific validation.

The aim of permaculture is to retain the rain as long as possible on the land. This is done by a series of swales that distribute the water widely and allow it to soak into the ground. The effect of this is to prevent run-off and erosion, build up the soil moisture and provide clean, filtered water in springs and streams downhill.
In a similar way, the Holistic Management of livestock aims to restore grasslands with the same effects.

Where these principles have been applied the observed effects on adjoining properties have been entirely beneficial, as would be expected.
