The mixing of mineral fertilizers to slurry or sludge to complete their fertilizing value becomes interesting with proper application systems that can mix both well. The mineral fertilizers becomes available more rapidly to the plants: the carrier to the root system being the slurry and not only the rain that can come sometimes later in the growing season. The application has to be done at ground level with dribble bars or injection systems. Those systems can be fitted to tanks or adapted to umbilicus systems that prevent ground compaction but are more time consuming for the set up and moving of the equipment. Four different applications methods for slurry and sludge are presented. The injection methods consume need high power input as the manure is injected at 12 to 18 cm with the wing coulters and 5 to 8 cm with the straight coulters, they are more time consuming and leave the ground cut up. Injection methods control well the odors and gas emission. Two other methods that leave the slurry at ground surface are presented: the slit roller and the dribble bar. The manure is applied at ground level and these methods allowing more odors and gas emissions. The slit roller opens a small grove in the soil of about 5 to 7 cm deep where the slurry is applied. As for the dribble bar, this system is the least power consumptive and the manure is applied on the ground level leaving the soil undisturbed. Splitter shoes can be adapted to the dribble bar thus limiting the shading of the plants when the manure is applied in growing crops. Irrigation systems using rain guns and sprinklers can also be used with de-fibered slurry however the odors and gas emissions are very important.<\/p>\n
This active fertilizers approach is very interesting but relay on proper controls and analysis of the slurry content, the soil, the crop needs and management and the mineral fertilizers to be added to complete the slurry or sludge. The application method has to be chose according to the crop as injection may not be suitable in all field and the work rate and required a lot of power. However the injection right at the application time prevents odors and gas emissions which make slurry application more acceptable to neighbors.<\/p>\n","protected":false},"excerpt":{"rendered":"
