Soybean( Glycine Max L ) Cultivation part 2
Lets we continue talk about soybean, we have talk about benefit of soybean crops and its history at part 1
Plant Media
1. Basically soybean want the condition of landfarm which do not too wet, but water remain to available or made available. Maize is indicator crop which both for soybean. Landfarm which is is good to be cultivated by maize, good is also cultivated by soybean
2. Soybean do not claim special landfarm structure as clauses grow. Even at less fertile farm condition and rather even sour also soybean can grow , as long as not suffused by water to cause the decaying of root. Soybean can grow good at various landfarm type, drainage and of good aeration enough landfarm
3. Compatible landfarms that is: alluvial, regosol, grumosol, and latosol of andosol. At landfarms of podsolik red turn yellow and landfarm concidering many quartz sands, growth of unfavourable soybean, except when given by organic manure addition or enough compost
4. New landfarms is first time cultivated by soybean, before all that required give by bacterium of Rhizobium, except landfarm which have cultivated by Vigna sinensis ( string bean). Soybean planted at chalky landfarm or ex- cultivated by paddy will give better result, cause of tekstur landfarm still good and only need fertilization by organic fertilizer
5. Soybean also require rich organic materials farm. Enough Organic materials in landfarm will improve repair process energy as well as is the source of food for microorganism, what finally will free element of nutrient for the growth of crop
6. Sandy landfarm can cultivate soybean, water and nutrient to crop for growth must enough. Landfarm concidering high hard, better be performed by repair the drainage system and aerasi so crop will not lack of oxygen and do not be suffused by big rain time water. To repair aeration , organic materials is vital importance manure
7. Tolerance acidity of landfarm as condition for grow
Height of Place of Varietas soybean have small seed, very compatible planted in the farm with height 0,5- 300 m from sea. While soybean variety have compatible big seed will better be planted in farm with height 300-500 m from sea level. Soybean usually will grow good at more than 500 m from the sea level .

3 Tree Fertilization Techniques by David Merriman
Landscape and urban trees typically grow in soils that do not contain sufficient elements due to disruption of the nutrient cycle by pavement, buildings and roads. Also, leaves, the driver of the nutrient cycle, are raked up before decomposing and micro-organism's can't break stuff down.
The key to tree fertilization is distributing the right amount of nutrients at the right time. Macro-nutrients are nutrients that trees need the most and is frequently deficient in a tree. Signs are reduced growth, smaller leaves and the yellowing of leaves. Secondary nutrients or nutrients needed in moderate amounts include phosphorus, potassium and sulfur. Micronutrients are nutrients that trees need in small amounts.
Many times it can be hard to tell what nutrient is deficient as the symptoms may overlap. However, it is worth finding as you may be wasting fertilizer on a tree that needs something different. If you see leaf discoloration or other unhealthy signs on the bark, test the tree to get an idea of what might be missing.
Tree fertilization application techniques vary based on the foliage, tree condition, the time of year and your preference for using "greener" techniques.
1. Surface Application
The fertilizer is broadcast over the ground surface using a spreader. The advantage is it's ease, with very little special equipment required. The disadvantage is lots of residual chemicals on your lawn.
2. Sub-surface Application
Sub-surface fertilization techniques are necessary when a tree is surrounded by turf grass or to limit chemical exposure. Turf grass absorbs nutrients more readily than tree root systems so the fertilizer must be applied below turf level. Subsurface fertilization techniques are also necessary where runoff water is common. Two common techniques are drill hole and injection.
The drill hole method involves drilling holes around the tree in concentric circles. Holes should extend to the drip line. This allows you to put fertilizer deep enough that turf grass won't reach it but shallow enough so it doesn't leach (drain away) especially during the rainy months of spring.
Liquid injection uses fertilizer, dissolved or suspended in water. The solution is injected into the soil using a soil injection system. Advantages are better distribution and the benefit of adding water directly into the root zone. A disadvantage is liquid injection can create dark, vigorous patches of grass. I sometimes recommend a lawn aeration and fertilization in conjunction with a liquid injection fertilization to combat that.
3. Foliar Application and Tree Injection
This involves spraying everything with FDA approved chemicals. Which is OK, as long as we remember that DDT was a federally approved chemical at one point! Foliar application is a short term fix to correct minor elemental deficiencies of micro nutrients. Typically spraying the leaves works best in spring, right before a period of active growth.
Implants and injections are for minor nutrient deficiencies. Tree implants and injections provide a systemic application and can be combined with insect control. The main advantage is that it completely eliminates any residue outside of the tree. However, because it involves creating holes in the tree it is limited to a once a year process and trees have to be large enough to handle it. I always look to see if a tree is water stressed before doing this.
Finally, trees may not require additional fertilization at all. Over fertilization can burn out leaves or cause a tree to grow too quickly resulting in frequent pruning or removal. In Denver or other dry climates, homeowners may fertilize a tree that actually just needs a deep root watering.
