Een optimale bodemkwaliteit draagt bij aan de wateropgaven en een betere opbrengst van landbouwgewassen. In de praktijk zijn veel landbouwbodems in meer of mindere mate verdicht, zijn de condities voor bodemleven niet gunstig, is het organisch stofgehalte niet optimaal en de beworteling beperkt. De laatste jaren zijn daarom projecten opgezet waarin...

After 8 years, the MAC field trial in Lelystad, the Netherlands, shows the effects of different fertiliser strategies, ranging from animal manure to plant compost to mineral fertiliser. The impact on yield, soil quality, soil health, environment and climate change is discussed. The trial is unique in monitoring the effect of so many types of fertil...

Understanding organic management practices is a key in developing sustainable organic farming systems. We report the results of four different organic fertilization strategies in a field trial on yields, soil quality and economic performance. We found highest yields and economic performance in two direct plant feeding strategies. One of these strat...

... In this study, we investigate the long-term effects of climate change on slow salinization by upward seepage of deep groundwater, which we expect to be the main cause of salinization in our study area, the Freepsumer Meer. We use the one-dimensional Soil-Water-Atmosphere-Plant (SWAP) model (van Dam, 2000), which allows for a specific parametrization of most processes (for details on the SWAP model and parametrization, see Sections 2.2 and 2.3), which are relevant for water and solute transport in the soil column and is currently widely used in studies concerning, for example, evapotranspiration (Bartholomeus, Stagge, Tallaksen, & Witte, 2015;Minacapilli et al., 2009), surface water management (Schipper et al., 2015), plant growth (Bonfante et al., 2017), and salinization (Kumar, Sarangi, Singh, Parihar, & Sahoo, 2015). We use long-term simulations with six different climate change scenarios with differing trends in F I G U R E 1 Overview of the study area. ...
... Also, data in Table (4) showed that application of compost led to increase soluble ions of Ca +2 , Mg +2 , K + and SO4 -2 while, decrease the soluble ions of Na + , HCO 3 and Clin the soil paste extract. The same trend was recorded by Miyazawa et al. (2004), Bokhtiar and Sakurai (2005), Koopmans and Zanen (2007) and El-Shouny et al. (2008). On the contrary, foliar application of magnesium by these amounts and application method had no effect on the soil properties under this experimental condition. ...
