How many bags of manure

Nutrient availability. So how much manure should you use? If you purchased bagged composted manure, the label on the package will tell you the nutrient content and application rates. The nutrient content of farm manure varies considerably depending on many factors.

The availability of the nutrients from the manure for plant growth will depend on the breakdown and release from of the organic components. Calculating nitrogen availability is more complex as it is dependent on microbial activity to make it available for uptake. Suggested rates of fresh manure or compost to apply to supply about 0.

A 5 gallon bucket holds about 25 lbs of fresh manure or compost, so you can estimate how much to use without actually weighing the materials. For example, use three buckets full of dairy manure without bedding spread over a 10 by 10 foot garden to add 0.

In most cases, manure application is based on its nitrogen content and estimated availability for the first growing season. It is important to have your soil tested to help determine if the level of phosphorus in the soil is building up too much in which case you probably should use a different type of fertilizer that has low or no phosphorus for a while , as well as to know if other plant nutrient needs are being met with manure alone.

Proper use of manure in the garden can supply your plants with nutrients and help improve soil structure. Adding too much manure can lead to nitrate leaching, nutrient runoff, excessive vegetative growth and, for some manures, salt damage. And using fresh manure where food crops are grown poses risks for contamination with disease-causing pathogens. Ask Your Gardening Question.

Composting at home. What is compost? Calculate compost needed: sample calculation for garden compost calculator Say you are creating a new garden that will be 10 feet by 5 feet in size. But do you know what? You can also make compost for FREE at your own home! Composting at home Making your own compost is an excellent way to reduce your food waste, decrease your greenhouse gas emissions, decrease your reliance on chemical fertilizers, and create a useful product to add to your garden and lawn.

What can you include in your compost? Dry leaves, grass clippings, and garden waste — you can even add in your Christmas tree if you chop it into small pieces first. Food scraps: Fruit and vegetable scraps, as well as eggshells and coffee grounds. STEP 1. We recommend:. STEP 2. Compost coverage calculator. Enter dimensions of application area in whole numbers Length in feet. Fill that jar with water and replace the lid, tightly.

Shake the jar vigorously and then let it stand for 24 hours. Your soil will settle out according to soil particle size and weight. Dig a hole 1 foot square and 1 foot deep and fill that with water. After that water drains away refill the hole with more water and time how long it takes that to drain away.

Anything over 6 hours and the soil drains too slowly and needs lots of organic matter to speed it up. Take a handful of your slightly damp soil and squeeze it tightly. When the pressure is released the soil should hold together in that clump, but when poked with a finger that clump should fall apart. What does your soil smell like? A pleasant, rich earthy odor? Putrid, offensive, repugnant odor? The more organic matter in your soil the more active the soil bacteria will be and the nicer your soil will smell.

How many earthworms per shovel full were there? Fewer than 5, according to the Natural Resources Conservation Service, indicates a soil that is not healthy. Those numbers are for single season gardening. If you use the same bed s for a full second season, like we do in the warm pats of TX, then you can double it with reapplication in between planting periods.

The weight will depend upon the density, which will mostly be determined by how much moisture is in the bag product. A 50 lb bag of Black Kow is about 0. So how much weight depends on the product. I like to apply new compost as a mulch, then incorporate it later. In that case you can put more on initially because in the months, at least, that it sits on the soil it will continued to degrade. Here is a link that might be useful: Colorado Master Gardening Notes.

If it were mine, I'd be comfortable with up to X that amount, if it were incorporated fairly evenly in the top 6" of soil. Putting more of a source of nutrients into soils is never a very good idea since that can create more problems then it would solve. Soils do not "bank" excess nutrients, they simply flow out with the water that drains away and creates pollution somewhere downstream, and the imbalance in nutrients can cause heatlh problems in the plants you are trying to grow which can mean insect pest and plant disease problems.

To know what is needed you need to know what is there and then you can determine what you need. You also need to take into account the rate of release of the nutrient from the nutrient source, the specific nutrient, and the form in which it is released, and soil composition.

In most good soils with sufficient cation exchange capacity CEC P is well retained, as are significant amounts of K and many mineral nutrients. The availability of P, Ca, and most metals has a large dependence on soil pH. N is the most mobile and fleeting, but soils can retain N precursors in the form of organic matter that provides for a slow release of N over time.

The question for N is whether there enough available in the right form when the plant demands it. Appreciable excesses are never good, and the spillover effect to the surrounding environment can be extremely troublesome. I would certainly not include compost on a ft garden in the same class as, say, overfertilizing a 10, sq ft lawn with granular , as far as pollution potential.
