By putting a layer of soil conditioner of about 75mm on top of the clay soil then dig it in and mix it with the soil, the organic matter will help break down the heavy clay lumps and make the soil more manageable. This is best done annually.

Skip MNZ4 - You have 8 inches of good soil in Zone 5 so I would think you could plant the bulbs at 6, maybe 7, inches. The problem is not that tulips won't do well in clay but it's that the clay underlayment acts as a barrier to good drainage and if you have really wet conditions this may, indeed, lead to rotting of the bulbs. The Hyacinths can go in at the same depth as the tulips while the Muscari can go in at 5 inches. See similar questions...

Nothing will change in terms of the approval and construction standards if a septic system is applied for under the Interim Ordinance. The Interim Ordinance will allow certain types of advanced systems to be installed (systems which have been approved in the past via a Board of Supervisors' variance). Standard septic systems will continue to be allowed under in the new Ordinance using the same approval and construction standards currently in place under the Interim Ordinance.

The key to gardening in Colorado is soil. Apply 3 inches of organics on top of your clay soil, which should be rototilled to a 6- to 10-inch depth. We recommend Nature's Yield® Compost. See similar questions...

Good soil does contain particles of clay, sand, and silt, however sand does not improve clay soil. Adding sand to clay makes cement! To improve any soil, always add organic matter. See similar questions...

Gypsum is generally added to provide a calcium source to displace sodium in the soil. (Gypsum is calcium sulfate, 22.5% calcium). For most soils in Montana east of the continental divide, the soil is already saturated with respect to calcium (as calcium carbonate or lime). Hence, adding gypsum to a soil already saturated with calcium simply elevates the concentration of calcium, favoring formation of calcium carbonate. See similar questions...

Polymer clay is an oven bake modeling material composed of polymers, resins, coloring agents, and fillers. When baked properly the finished product cures into a tough, very flexible and durable solid material. The flexibility enables the finished piece to be dropped or handled without breaking. It is not rock hard like an "earth clay" where it will shatter if dropped. See similar questions...

The weight given to standardized admissions exams varies from program to program and discipline to discipline. If your exam score is not reflective of your academic accomplishments and capabilities, it is often a good idea to ask one of your faculty recommenders to address it in the letter. This can be particularly effective if you have taken advanced courses or done independent study with that professor. See similar questions...

Answer: One of the most popular organic fertilizers is fowl manure which, if allowed to sit for a few days gives off Ammonia. So fowl manure contains most of its Nitrogen in the Ammonia form. Now most plants like their Nitrogen in the Nitrate form, and soil bacteria help them by converting Ammonia Nitrogen to Nitrate Nitrogen. See similar questions...

No, they don’t break or chip easily. The tiles, which are manufactured in Ohio from local clay, are made of dense materials which can be fired at a very high temperature, making them very hard and durable. They have very low moisture absorption, which means they are excellent in a freeze-thaw climate and also resistant to mold and lichens. See similar questions...

Testing has shown that manure will not adequately seal certain soil types. The Department has set the requirement of 15% clay to insure adequate sealing will take place. Do to increased hydraulic pressure on deeper waste storage ponds, additional testing and/or additional soil liner thickness will be required. See similar questions...

Soil is made up of a variety of solid particles most of which are oxides of inorganic elements, it also has organic component which makes soil conducive to plant growth. See similar questions...
