Who is the LandManagement module for?

The LandPKS LandManagement Module is intended for farmers and gardeners. It is a simple tool for farm and garden record-keeping. By utilizing the video and text tutorials and the ‘help’ texts accessible by clicking on the question mark icons, users of all skill levels will be able to easily learn how to  track farm/garden activity. LandPKS can be downloaded onto almost any tablet or smartphone and the LandManagement Module, like all of the LandPKS modules, can be used for K-12 education.

What does it do?

LandManagement allows users to quickly and easily track management activities. You begin with a basic Field Description, which includes the area of the field and the first year it was cultivated. Then, using the Field Calendar, you can track a wide range of activities and events on your land including:

  • Planting dates and yield
  • Weed and pest management
  • Nutrient management and compost applications
  • Irrigation and rainfall (recorded separately)
  • Tillage
  • Crop residue management
  • Erosion control

In the module’s Report tab, generate and download a PDF report about your land for any given period of time.

What is the LandInfo Module for?

The LandPKS LandInfo module is designed for rapid soil characterization and identification. In LandInfo, users can access soil and ecological site information based on both location and user inputs. The LandInfo Module is useful to anyone who is interested in characterizing and identifying their soils. The module can be used for land management as well as in educational contexts.

Using the LandInfo module, users can identify their site’s soil type (SoilID) and determine  its Land Capability Class (LCC), essential information for sustainable land-use planning and management. To learn more about Soil Identification and Land Capability Classification, take a look at the SoilID and LCC articles.

You can also watch our video tutorial about how to use the LandInfo module.

Features of the LandInfo Module

In the app’s Data Input tab, the LandInfo module considers five defining aspects of soil: Land Use, Land Slope, Soil Texture, Soil Limitations, and Soil Color.

  • Land Use asks the user two questions: 1) What is the Land Cover on the site?, and 2) Is the site grazed? Under Land Cover, the user can select from 9 simple illustrations of possible land covers, from forest to village to water. Under Grazing, the user can select from 8 illustrations, ranging from not grazed, grazed by livestock, and grazed by wildlife.
  • Land Slope is about the angle of the land and the way it directs water. Under Slope, the user can select from 7 illustrated slopes or use the slope meter. Under Slope Shape, a series of 6 illustrations depict the shape of the slope both in the down-slope direction (left column of illustrations) and the across-slope direction (right column of illustrations). The user can select one illustration from each column. For example, the slope might be linear in the down-slope direction but concave in the accross slope direction, resulting in a linear/concave slope shape.
  • Under Soil Texture, users can begin to define what kind of soil they have at their sites, layer by layer. Is the surface texture a sand, silt, loam, or clay? Does it have rock fragments? By analyzing soil properties by depth, the LandInfo module predicts soil infiltration and plant available water-holding capacity (AWC). AWC estimates can be adjusted to account for variable levels of soil organic matter (SOM). The LandPKS Texture Guide provides easy, step-by-step instructions for soil texture identification. Users may also enter Rock Fragment Volume data and the Bedrock Depth in this tab.
  • Soil Limitations such as deep, vertical cracks in dry soil, salt found on the surface, high flooding risk, low PH, surface stoniness, water table depth and soil depth have major implications for land use. In most instances, these limitations can limit root growth and crop production; when not taken into account, they can lead to long-term degradation of the land.
  • Finally, the LandInfo module in the LandPKS mobile app contains the Soil Color tool. With this tool, users can define soil color using a phone’s camera and a standardized reference card. For more information about soil color and using the LandPKS soil color tool, refer to our article about soil color.

The LandInfo Module has been designed to accommodate users with different levels of experience, from the backyard gardener to the natural resource professional. By utilizing the video and text tutorials, the texture guide, and the ‘help’ text accessible by clicking on the question mark icons, users of all skill levels will be able to characterize their soil and gain a better understanding of its potential.

What is soil health?

Soil health, also referred to as soil quality, is defined as the continued capacity of soil to function as a vital living ecosystem that sustains plants, animals, and humans. Soil is an ecosystem that can be managed to provide nutrients for plant growth, absorb and hold rainwater for use during drier periods, filter and buffer potential pollutants from leaving fields, serve as a firm foundation for agricultural activities, and provide habitat for soil microbes to flourish and diversify to keep the ecosystem running smoothly. Soils have both inherent and dynamic properties. A soil’s dynamic properties depend on how the soil is managed. Understanding soil health means assessing and managing soil so that it functions optimally now and is not degraded for future use. By monitoring changes in soil health, a land manager can determine if a set of practices is sustainable. (Information from USDA-NRCS.)

Who is the SoilHealth Module for?

Farmers, gardeners, and other land managers.

What does the SoilHealth Module do?

The LandPKS Soil Health module allows users to input and track data about the  dynamic properties of soil that are important for productivity and sustainability. Soil health indicators, when observed over time, can provide land managers critical information about how management practices are affecting their soil’s health. Users can track data over time using the Field Calendar and then download PDF reports about their soil health in the Reports tab.

The SoilHealth module currently allows users to record the following soil health indicators (field and laboratory).

Field indicators:

  • Erosion indicators, including water flow patterns, rills and gullies. Erosion indicators reflect soil movement and loss from the site. They can also be used to detect excessive runoff, which can reduce water availability for plants. Water flow patterns are soil surface patterns caused by runoff. They are made visible by litter, soil, and gravel redistribution. Steep cuts may occur on one side.
  • Compaction layers. A compaction layer is a near-surface layer of dense soil that is hard for crop roots and water to penetrate. Record depth to top of compaction layer, thickness of compaction layer, level of development, and extent.
  • Aggregate stability, or the ability of soil aggregates to resist collapsing into smaller pieces due to tillage and wind or water erosion
  • Soil Smell. Sweet, earthy soil smell indicates a biologically active soil. Soils that lack smell may have little biological activity. Soils with a stagnant, swampy or mineral smell may suggest a lack of oxygen and therefore poor soil structure.
  • Biological Activity. Soil is filled with microscopic and larger organisms that perform many vital functions including converting dead and decaying organic matter, as well as minerals, to plant nutrients. They affect soil structure and therefore water availability and soil erosion. They can protect crops from pests and diseases. The SoilHealth module allows you to track if there are many, some, or no signs of organisms in the soil.

Laboratory indicators

  • Soil Organic Carbon/Matter. Soil organic carbon (SOC) is a measurable component of soil organic matter (SOM). Reduction in soil organic matter levels lead to deficiency of nutrients for crops, decrease in soil aggregate stability and water holding capacity, and decline in soil biological activity.
  • pH. Soil pH is a measure of soil acidity (pH<7) or alkalinity (pH>7). Soil pH levels that are too high or too low lead to deficiency in many nutrients, decrease in crop yield, and decline in soil biological activity.
  • Electrical Conductivity (EC). Soil electrical conductivity (EC) is a measure of the amount of salts in soil (salinity of soil). EC that is too high can reduce crop yields and even prevent some crops from growing. It reduces water and nutrient availability for both plants and soil organisms.
