Changes of inner teat morphology caused by the milking process and by incomplete milking during dry-off as assessed by innovative technologies
(2020-03-03)
In dairy farming, the timing of the lactation cycle and the way of milk removal differ considerably from the natural conditions. Ensuring good health and wellbeing of farm animals is of great interest from both an economic ...
Studies on the effect of exogenous amino acid application on nematodes
(2020-03-02)
Plant parasitic nematodes are considered as key pathogens in agricultural crop production. They cause substantial yield losses in numerous crops and across all climatic regions worldwide. Antagonistic effects on various ......
The revision of the German Fertilization Ordinance in 2017: Analyzing economic and environmental impacts at farm-level
(2019-10-31)
The Fertilization Ordinance (FO), implementing the EU Nitrates Directive in Germany, is the core regulation to limit the loss of reactive nitrogen and phosphorus from agriculture. It was revised in June 2017 after environmental ...
Extreme weather events in Sudan Savanna Region of West Africa: agricultural impacts and adaptation
(2019-11-14)
Climate and weather extremes generally lead to crop yield, income and consumption losses. Despite their occurrence at the farm level, very little has so far been done to empirically assess weather risks and their effects ...

The Upper East region is one of the poorest regions in Ghana with an estimated 90% of the people living in rural areas being peasant farmers. In many instances, farmers use their land unsustainably thus worsening the already ...
Phosphorus forms in fertilized arable soil profiles and related 33P uptake
(2019-09-13)
Arable soils usually store several thousand kg phosphorus (P) per ha, thus far exceeding the recommended P fertilizer dose to sustain crop yields. However, the soil profile is frequently not considered in fertilizer ...
