Western US – One of the best spring forage sources for honeybees. Blooms 45–60 days and continuously produces nectar throughout the day. Can be seeded several times per year. Prefers 3 ft of topsoil. 180–1,500 pounds honey per acre, depending on soil quality and depth; 300–1000 pounds of pollen. [9] G, H Plantain: Plantago Major ...
Modern commercial apple orchards, by contrast and as one example, are often "high-density" (tree density above 370/ha or 150/acre), and in extreme cases have up to 22,000/ha (9,000/acre). These plants are no longer trees in the traditional sense, but instead resemble vines on dwarf stock and require trellises to support them. [7]
When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]
A 15-ton crop of onions uses up to 19 lb of sulfur and 4 tons of alfalfa uses 15 lb per acre. Sulfur abundance varies with depth. In a sample of soils in Ohio, United States, the sulfur abundance varied with depths, 0–6 inches, 6–12 inches, 12–18 inches, 18–24 inches in the amounts: 1056, 830, 686, 528 lb per acre respectively.

An open-centred crown on a short trunk of less than 1 metre (3 ft 3 in). This is a traditional and popular form for apple trees. Bush trees are easy to maintain and bear fruit at a young age. Final height is between 2 metres (6 ft 7 in) and 5.5 metres (18 ft), depending on which rootstock is used. [1]

In most climates, alfalfa is cut three to four times a year, but it can be harvested up to 12 times per year in Arizona and southern California. [44] [45] Total yields are typically around 8 tonnes per hectare (3 + 1 ⁄ 2 short tons per acre) in temperate environments, but yields have been recorded up to 20 tonnes per hectare (9 short tons per ...
In one example, a ten-year experiment in Malawi showed that, by using the fertilizer tree Gliricidia (G. sepium) on land on which no mineral fertilizer was applied, maize/corn yields averaged 3.3 metric tons per hectare (1.5 short ton/acre) as compared to 1 metric ton per hectare (0.45 short ton/acre) in plots without fertilizer trees or ...
