METHOD OF TESTING OF GRASS COVER OF FOREST COASTAL MEADOW Russian patent published in 2014 - IPC A01G23/00 A01G7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of forestry and landscape management and can be used in biotechnology and biochemical evaluation of the grass cover on the meander inundable floodable and upland meadows and meadows of forests. The method comprises the allocation within the water protection zone visually on the map or by full scale the site of the meadow with the test grass cover. Then on this site downstream the river or its feeder the groups of test sites are marked up and down the coastline. When marking the constant distance between the centres of the test sites along and across the river is taken into account, and after cutting the grass samples they are subjected to weighing and determine patterns of influence of distance from the riverbank and along it to the change in weight of samples of freshly cut grass. The meadow site even by the relief with test grass cover is allocated between the parallel to each other road and the coastal edge of a small river or its feeder. And if there is forest stand on the side of the site between the road and the riverbank, the distance from the edge of the site to the edge of the forest is measured. On the site of the test grass cover the grid mesh of the sample sites is taken uniform in both directions along and across the small river. And the location of the sample sites is taken along the longitudinal and transverse lines with equal distances relative to the bank of the small river or its feeder. And the distance from the edge of the coast to the first longitudinal line of the sample sites is taken not less than the spacing between the grid mesh lines, and the additional lines of location of virtual sample sites with zero mass of samples are taken as the riverbank and the edge of the road from the side of the grid mesh of the meadow site with test grass cover.

EFFECT: method enables to extend the functional capabilities of testing the grass cover, in particular, meander meadows and forest meadows, to improve the accuracy of measurement and analysis of distributions of green mass of grass samples on the test sites, and to identify complex patterns of influence of the distance from the river, road and forest to the centers of the sample sites on the yield of meadow grass.
