A mathematical model was developed to describe the rates of drying of perennial ryegrass across a number of different treatments at mowing and after mowing and different weights of grass per unit area.
The effects on drying rate of five weights of grass per unit area (1·5, 3, 6, 12 and 24 kg [fresh material] m−2), three treatments at mowing (no treatment, mower-conditioned, flail-treated) and three treatments after mowing (no treatment, inverted, mixed) were examined in a 5×3×3 factorial experimental design.
In the experiment, weight change of grass in wire-mesh trays was measured in the field over 2 d (32 h).
So like mechanics tuning a race car engine, Mr. Lumsden and his fellow dairy farmers keep close track of the weight of the grass in their pastures, precisely measure its protein and sugar content, and produce computer charts tracking how much they have left to feed their cows through winter.
The hardest thing about bringing cattle to market weight on grass -- rather than fattening them in feedlots for the last six months of their lives -- is that you got to have cowboys to do it.
Filled to capacity, air filters at Cedar Grove Composting, King County's largest private composting operation, began to malfunction under the weight of dense, wet grass, the most odorous component of compost.
It has been reported that the daily ration (the relation of the total weight of feed taken in a day to the weight of the fish) of grass carp may reach 49.9% when feeding on aquatic plants [ 17].
A grass belonging to the Andropogonaceae, sorghum ranks fifth among world crops in weight of grain produced [ 1].
This paper attempts to show the relative weight of plant life (trees, grass, orchards, etc).
Both concentrate mixes were limit-fed at 0.8% of body weight and grass hay was offered ad libitum.
