在1984年8月和10月，在牛奶和面团成熟阶段的整个玉米植株青贮，分别为45和40天。13个装有牧草样品的网袋被埋在筒仓内的不同位置，以确定在保护期内的变化和损失。将热电偶线和小直径塑料管连接到每个袋子上，用于温度和气体测量。空气在上层的渗透比在内部快得多。在密封良好的掩体中，干物质损失为3.9 - 7.4%，在空气渗透的位置高达36%。记录了空气渗透到青贮饲料中的速率和掩体中各个地点的温度。青贮饲料中CO2和N2含量之间的相关性非常高（r2= 0.995），而氧水平接近于零。
Whole maize plants at the milk and dough maturation stages were ensiled in August and October 1984, for periods of 45 and 40 days, respectively. Thirteen net bags containing herbage samples were buried at different locations within the silo to determine changes and losses during the conservation period. Thermocouple wires and small‐diameter plastic pipes were connected to every bag for temperature and gas measurements. Air penetration in the upper layer was much faster than in the inner parts. Losses in dry matter of 3.9‐7.4% were found in well sealed sites in the bunkers, and of up to 36% at locations where air penetrated. The rate of air penetration into the silage and temperature at various sites in the bunker were recorded. Correlation between CO2, and N2, contents in the silage was very high (r2= 0.995) whereas oxygen levels were close to zero.
