Soil Characteristics. Pursuant to requirements contained in D.C. Official Code § 42-608(b) the District hereby gives notice to the Developer that:
(a) The characteristic of the soil on the Property is described by the Soil Conservation Service of the United States Department of Agriculture in the Soil Survey of the District of Columbia published in 1976 Soil Maps of the District of Columbia at the back of that publication; and
(b) for further soil information, Developer may contact the District of Columbia Department of Environmental Services or the Soil Conservation Service of the Department of Agriculture. The foregoing does not constitute a representation or warranty by District.
Soil Characteristics. The Purchaser has been advised pursuant to the provisions of Title 45, Section 308 of the District of Columbia Code concerning Soil Characteristics, that the soil of the land upon which the Condominium is located is noted in the Soil Survey of the District of Columbia as Urban Land-Beltsville-Chillum association. The Purchaser has been further advised that it may obtain further information with respect thereto by engaging a soil testing laboratory, the District of Columbia Department of Environmental Services or the Soil Conservation Service of the Department of Agriculture.
Soil Characteristics. The characteristics of the soil of the Property, as described by the Soil Conservation Service of the U.S. Department of Agriculture in the Soil Survey Book of the District of Columbia (Area 11), published in July, 1976, and as shown on the soil maps of the District of Columbia at the back of that publication is Urban Land. For further information, Purchaser may contact the Soil Testing Laboratory, the District of Columbia Department of Environmental Services, or the Soil Conservation Service of the U.S.
Soil Characteristics. District hereby states that, to the best of its knowledge, the soil on the Property has been described by the Soil Conservation Service of the United States Department of Agriculture in the Soil Survey of the District of Columbia and as shown on the Soil Maps as [Soil – Urban Land and Urban Land- Chillum complex, 0 to 8 percent slopes]. Developer acknowledges that, for further soil information, Developer may contact a soil testing laboratory, the D.C. Department of Environmental Services or the Soil Conservation Service. The foregoing is set forth pursuant to requirements contained in D.C. Official Code § 42-608(b) and does not constitute a representation or warranty by District.

Soil Characteristics. The soil samples were tested at eight locations during post-monsoon and partly winter season covering various land uses. It has been observed that the pH of the soil in the study area ranged from 7.6 to 8.2. The electrical conductivity was observed to be in the range of 110 µs/cm to 412 µs/cm. The nitrogen values range between 29.7-118.4 kg/ha. The phosphorus values range between 32.6 to 434.9 kg/ha. The potassium values range between 51.8 – 676.9 kg/ha. The soils from the study area indicate that medium fertility due to their NPK content.
Soil Characteristics. Soil characteristics in October 2013 were similar for both Muck and LR Cap treatments (Figure 9). Total P concentrations were elevated in the newly-accrued sediment layer (266 and 360 ± 60 mg/kg, for Muck and LR Cap treatments, respectively), as compared to the muck soil layers (134 – 180 mg/kg) from either treatment (Figure 9). Calcium enrichment of the newly-accrued layer (23 and 22 % for Muck and LR Cap, respectively), relative to underlying muck soil layers (2 – 5 % Ca), was evident in both muck and LR Cap treatments. Calcium enrichment can effectively dilute the P content of soils, but in the present study calcium contents in the accrued layer were similar between treatments and may have provided additional P sorption capacity to this new soil material. Total N and organic C contents were reduced in the accrued sediment layer, likely the result of dilution by Ca enrichment of that surficial layer. Enzyme activity in the sediment increased in the accrued layer, relative to the upper (0-5 cm) muck layer. Muck-based mesocosms without limerock exhibited consistently higher potential for both APA and PDE than did the LR Cap soils within respective soil layers (Figure 10). Soil pH, by contrast, was similar between treatments and between accrued and 0-5 xx xxxx layers.
