https://doi.org/10.1007/978-3-030-05651-3100 years..In the past, animal manure was highly valued as a source of plant nutrients. Animal manure can still be considered as such, the more so as its intrinsic value has risen due to higher soil fertility levels and the use of mineral additives in animal nutrition. The need for these nutrients h

Guilty Grief and Ecological Mourning, N utilization in cows grazing intensively managed pastures, is 15 to 25%. When young leafy grass is the sole feed this figure cannot be altered substantially without reducing animal performance. Supplementing the diet of grazing dairy cows with a low-protein, high-energy feed (special concentrates

Bart Rossmann,Tim Peterson,John Drakeyears. In two experiments, surface application of slurry was included; all slurry applications were made in the spring. In each experiment three rates of slurry application were used, the maximum rates were 40tha. yr. and 80 or 90t ha.yr. for the surface-spread and injected treatments, respectively.

Ecologists and Ethical Judgements of treatment, slurry properties and the effect of slurry applications upon crop growth can change in a wide range of ways. Positive as well as negative yield effects can occur. The fertilising efficiencies of different slurry processing methods can be summarised as follows:.In general appropriate s
