GA Landscape key terms

The defined particle-size mixture of sand, silt and clay under the relevant classification convention, distinguished from aggregation and arrangement.

The aggregation and arrangement of soil components and pores, which can affect air and water movement without changing the underlying texture proportions.

A measure of relevant positively charged ion retention under the specified method, not the total availability of every nutrient to every plant.

A sample matching the actual zone and question being examined, rather than a mixture that conceals important differences among plant or soil conditions.

The relevant transition between stem and structural roots, which must be identified rather than assumed from the visible potting surface.

The selected upper plant material in a compatible graft arrangement, distinct from the rootstock and from a newly fixed genetic cross.

Production from suitable plant material without sexual seed formation, which can preserve the selected genotype under the relevant biological conditions.

A record of the species, timing, site, recent work and environmental conditions used to interpret symptoms instead of guessing from one appearance.

A diffuse contribution from relevant landscape or production pathways rather than a single identified discharge pipe or other defined point.

Nutrient enrichment that can promote excessive biological growth and related oxygen problems under the actual receiving-water conditions.

The variety of relevant biological life at appropriate levels, not merely the number of large visible animals in one location.

The supported population level under defined environmental and resource assumptions, which can change with time and management.

The residual interest represented by assets minus liabilities under the stated business accounting basis, rather than cash available in the bank.

The timing and amounts of actual cash receipts and payments, distinguished from profit measured on another revenue and expense basis.

The value of the next-best alternative forgone by a decision, which can include relevant monetary and nonmonetary considerations.

An estimate allowance for defined uncertainty, which does not by itself authorize a change to contracted scope or a guaranteed price increase.

A system transferring relevant rotational energy to an implement, whose presence entails actual guarding and energy-control considerations.

An input decision responding to mapped or sensed variation, requiring actual data quality and interpretation rather than GPS location alone.

The stated relationship between drawing and actual dimensions, which must be combined with compatible units and relevant tolerances.

An organized learning arrangement with appropriate responsibility, records and feedback, distinct from unrestricted independent hazardous-work authority.

The actual planting, structural, electrical, irrigation or pesticide work proposed, each assessed for its relevant professional and local requirements.

An actual licensing-scope policy that must be read within its limits rather than treated as a claim that every landscape project is exempt.

Relevant existing boundaries, utilities, structures, water pathways and environmental conditions that can change a project’s appropriate design and responsibilities.

The actual agreement and record governing a scope, cost or schedule change, rather than an informal assumption that an estimate allowance grants permission.
